Draft Document for Review February 7, 2020 3:15 pm 8464ch08_Migrate.fm 8.1.2 Tape-based migration 8.2 Migration between TS7700s Migration from a TS7700T to another by using physical volumes, also called  outboard VTS  migration , is possible depending on the target configuration. It provides an upgrade path for  old VTS models to a newer TS7700T if the VTS system contains only 3592-formatted data.  The outboard migration is offered as IBM Data Migration Services for Tape Systems.  Outboard migration provides the following functions: GLYPH<SM590000> Planning for migration, including considerations that are related to hardware and z/OS GLYPH<SM590000> Project management for this portion of the project  GLYPH<SM590000> Assistance with the integration into a complete change plan, if required  GLYPH<SM590000> The migration of data from an older TS7700T to a newer model Work with your IBM service support representative (IBM SSR) for more information about  IBM Migration Services for Tape Systems. These services are available from an IBM  migration team and can assist you in the preparation phase of the migration. The migration  team performs the migration on the hardware.  When migrating data from a VTS to a new TS7700T that is installed in the same tape library,  the process is called  data migrate without tape move . If a source VTS is attached to one tape  library and the new target TS7700T is attached to another tape library, the process is called  data migration with tape move . When a source VTS is migrated to a TS7700T, or two VTSs  are migrated to the same target TS7700T, the process is called  merge .  The method that is described in 8.1.1, “Host-based migration” on page 298 also can be used  for data migration between TS7700s. However, other preferred methods are available for this  purpose that do not need to involve a host for data movement. These methods are explained  in the following sections. The user should select the most efficient approach, depending on the case: GLYPH<SM590000> Host-based migration: Uses host cycles and operation involvement for data movement. GLYPH<SM590000> Frame replacement migration for TS7700T: – Option to replace an older TS7700T model with an entirely new machine. – New (“target”) TS7700T takes the identity of the old one (“source”), so the replacement  operation is transparent to other cluster members of the same grid. – It does not involve host for data movement. – It depends on all data that is in the source machine to include completed copies to  physical tape in advance to actual frame replacement.  GLYPH<SM590000> Join and Copy Refresh processing: – Used for data migration to empty TS7700 inside the same grid – Does not involve host for data movement – Does not use physical tape volumes GLYPH<SM590000> Migration service offering: – Used for data migration to another TS7700 inside the same grid – Does not involve host for data movement – Does not use physical tape volumes – Multiple concurrent migrations are allowed inside the same grid Chapter 8.
