2 File and Networking Services White Paper Simplifying Data Migration through Novell Storage Manager Data Migrations Migrating data from one network storage device to another is an inevitable burden faced by all organizations at one time or another. Data migrations are necessary on many occasions and for many reasons, such as when: Data outgrows server capacities. You need to consolidate multiple servers to a single server or storage area network (SAN). You deploy a new network operating system. Data migrations are normally huge IT projects, requiring you to copy each file from a source file server to a destination file server or network attached storage (NAS) device. With potentially terabytes of data to move, the process can be tedious. It can also be disruptive to users who cannot access files that you ve targeted for migration. But it s the post-migration work in migrations of this sort that really makes the process burdensome. The copying process resets metadata, time stamps and, most importantly, the rights pertaining to migrated data, making it necessary to reestablish these rights individually for each migrated file. It s no wonder that so many organizations delay migrating their data from old to new servers. For example, many Novell network owners have resisted migrating from their NetWare platform to the newer Open Enterprise Server platform. Unfortunately many organizations, including most of these Novell customers, are unaware that Novell Storage Manager can greatly alleviate the data migration burden by providing the means to automate data migration while retaining all rights, metadata and timestamps. Novell Storage Manager Novell Storage Manager automates management throughout the full lifecycle of user and group storage. Leveraging the network 2

3 directory (Novell edirectory or Microsoft Active Directory), Novell Storage Manager automates a comprehensive set of storage management tasks based on events, identities and policies. Directory events trigger policy-based Novell Storage Manager actions. Policies can specify: Where to create user home directories and group directories What specific files to provision inside the directories, along with rights and storage quota settings Where to move home directories and what rights and quota to modify when administrators move users in directory services And much more How Novell Storage Manager Enables Data Migrations Novell Storage Manager enacts data migrations within Novell environments by using policies, and from Novell to Microsoft environments using its Cross-Empire Data Migration subsystem. Settings within Novell Storage Manager policies enable home directory and group directory migrations from a Novell source server to a Novell target server. For example, a policy setting can dictate how to move home directories residing on a NetWare server to a specific volume on an Open Enterprise Server 11 machine and in the process, maintain all file rights, trustee assignments, metadata and timestamp information. Recently, Novell Storage Manager added Cross-Empire Data Migration. Cross-Empire Data Migration is a subsystem within Novell Storage Manager that migrates file system data from Novell networks to Microsoft networks, including their corresponding storage infrastructures and identity and security frameworks. Through a wizard interface, Cross-Empire Data Migration quickly and automatically moves data based on a variety of scenarios, such as moving files for multiple users and groups directly to their intended locations across multiple servers or shares in a single operation all while preserving important file system metadata. Cross-Empire Data Migration supports three data movement types: 1. User storage: Migrates data from a Novell home directory to a Windows home folder through either a source container or source file system path. You can also provision the Windows home folder as a part of this process. 2. Collaborative or group storage: Migrates data from a Novell group home directory to a Windows group home folder through either a source container or source file system path. 3. Direct folder storage: Migrates a directory based on distinct file system paths on the source and target networks. The remainder of this paper presents data migration scenarios and explains how Novell Storage Manager can simplify each. Scenario 1 Novell NetWare to Novell Open Enterprise Server 11 Data Migration In this scenario, you have deployed Novell Storage Manager in the edirectory tree of which both the source NetWare server and destination Open Enterprise Server 11 machine are members. If you are already using Novell Storage Manager to manage the home and group directories you want to migrate, you simply need to: 1. Edit the Novell Storage Manager policy that specifies the NetWare server target path and change it to the desired target path on the Open Enterprise Server 11 destination server. 2. Use the Enforce Policy Paths management action to initiate migrations from the source to the destination server. 3

4 File and Networking Services White Paper Simplifying Data Migration through Novell Storage Manager If you are not using Novell Storage Manager to manage the home and group directories you want to migrate, you need to: 1. Create a Novell Storage Manager policy specifying the current location of the directories you want to migrate as the target path for the policy. 2. Use the Manage management action to catalog the directories. 3. Edit the Novell Storage Manager policy that specifies the NetWare server target path and change it to the desired target path on the Open Enterprise Server 11 destination server. 4. Use the Enforce Policy Paths management action to initiate directory migrations from the source to the destination server. After you ve run the Enforce Policy Paths action, Novell Storage Manager begins the process of moving home and group directories, unless one (or more) of the following statements is true: The home directory s user is logged in to the NetWare server. The home directory s user has a file open from the home directory. The move schedule does not allow Novell Storage Manager to move the directories during this time of day. I love Novell Storage Manager. It s one of the best things we have here. It saves me some time almost every day. ERIC FELDMAN Network Services Engineer Garland ISD The Enforce Policy Path option ensures user home directories and group directories are located in the target path specified in the policy. If the directories are not presently located in the target path, Novell Storage Manager automatically moves them to the specified target path. Case Study #1 Garland Independent School District With an enrollment of over 57,000 students, the Garland Independent School District (ISD) is the second largest district in Dallas County and one of the largest districts in the state of Texas. The district oversees two preschools, 47 elementary schools, 12 middle schools, seven high schools and other non-traditional education centers. Eric Feldman is a network services engineer at Garland ISD and has relied on Novell Storage Manager for years to manage the thousands of student home directories the district s Novell servers host. Recently, Feldman was involved in the migration of over 35,000 student home directories from NetWare servers to Novell Open Enterprise Server 11 servers. The process was very simple because all the district had to do was change the target path and then run Enforce Policy Paths. Feldman remarked: I love Novell Storage Manager. It s one of the best things we have here. It saves me some time almost every day. 4

5 Scenario 2 Novell NetWare or Open Enterprise Server to Microsoft Windows Data Migration In this scenario, you deploy Novell Storage Manager in your Microsoft Windows network and use Cross-Empire Data Migration to move the data for multiple users and groups directly across multiple servers and shares to their intended locations. Furthermore, the migration maintains ownership, quota and metadata information while transforming Novell rights and trustee assignments into equivalent Microsoft rights and permissions. The following steps summarize the data migration process as documented in chapter nine of the Novell Storage Manager 3.0.x Administration Guide for Active Directory ( storagemanager3/). 1. Complete the prerequisite tasks. 2. Create a migration proxy account to enable communication between the edirectory source and Active Directory destination. 3. Create an identity map for associating users, groups and containers that are the owners and trustees of the Novell network data with the corresponding data owners on the Microsoft network target. 4. Use the data migration wizard to perform any of the following data migration types: User to user data migration Folder to user data migration Folder to group data migration Folder to folder data migration Case Study #2 Hämeen Ammattikorkeakoulu (HAMK) University HAMK University s main campus is located in Hämeenlinna, Finland. Student enrollment The Cross-Empire Data Migration subsystem features an easy-to-use wizard interface that lets you view and edit source and target objects and their locations. In this example, the contents of user home directories in edirectory are being associated with user home folders in Active Directory. is approximately 8,000 and the university employs a staff of about 800. For the past four years, the university has relied on Novell Storage Manager to automate the management of its student and faculty network home folders, which are located across multiple NetWare and Open Enterprise Server servers. In 2012, the university switched network operating systems from Novell to Microsoft. As part of this change, the IT staff needed to migrate 12 million scattered files located in more than 8,000 home folders to a single NetApp attached storage device. The IT staff chose to use the Novell Storage Manager 3 Cross-Empire Data Migration subsystem. The university was pleased with the migration s outcome.
