Hello Javier

There are 2 things you can do with virtualization:

  • Virtualize external volumes in a pass through and then migrate internally. 
  • Virtualize external volumes to use as a capacity pool on a Hitachi Array.

For the first use case you can take a look here:

Virtualize External Volume

After you virtualized it you can migrate it to an internal pool at your convenience.

there are 3 phases to migrate old data this is UVM migration

1.Virtualisation - see in video create HOST group for new array in old vsp 

Old array is virtualized behind the Exxx.

Virtualizing in Ops Center: E-VOL will get LDEV ID assigned during GUI process
Virtualizing with raidcom: must do separate command to map LDEV ID to E-VOL

2.Cut over-

- Shutdown hosts being migrated (for clusters with SR/PGR, must shutdown before virtualization)
- Remove zones to source array ports
- Add zones to target array ports
- Boot up servers and verify virtualized LUNs present
- Verify multipathing, file systems and Apps/DB
- Migrate data from External Volumes to Internal Volumes (EXXXDP or HDT volumes) using:
a) Migration Volumes in Ops Center Admin
1) Navigate to 'External Volumes' window
2) Select volumes to migrate
3) Click 'Migrate Volumes' button
4) Select 'Target Pool'
5) Set Volume Settings 
6) Task Settings: choose Migrate Now;
     set Migration Task Name=
7) Click Submit"
