SLS to ABS Migration

Hello,

I'm working a project to move a customer from SLS V2.9h to ABS V4.4/4.5.

I've seen the documentation about loading SLS vms saveset history data into ABS catalogues does this same technique work to load SLS RMU backup saveset history data into ABS catalogues?

Thanks

David,

There's a difference between SYSBAK files which execute backup types (VMSBACKUP, RMU) and History sets.

From TAPESTART.COM:
$! History set for Manual backups
$!
$ HISNAM_4 := OPER
$ HISDIR_4 := SLS1:[SLS$FILES.HIST.OPER]
$ HISTYP_4 := BACKUP
$!
$! History set for RMU backups.
$!
$ HISNAM_5 := RMUAIJ
$ HISDIR_5 := SLS1:[SLS$FILES.HIST.RMUAIJ]
$ HISTYP_5 := RMUBACKUP
$!
$ HISNAM_6 := RMU_DAILY
$ HISDIR_6 := SLS1:[SLS$FILES.HIST.RMU_DAILY]
$ HISTYP_6 := RMUBACKUP

Basically three type of history sets defined, two designated RMU"type" one OPER in my TAPERSTART.

These can be imported into ABS as ABS catalogs.

Section B.2 of the ABS Operations Guide has a mapping of the SLS to ABS equivalancies.

Importing data from SLS saves to an ABS environment sounds easy but it is not hassle free. I know of a couple of users who decided after worrisome attempte to switch to ABS completely but keep their SLS environment around for a while to be able to restore older backups.

You can import BACKUP save sets from SLS into ABS catalogs. Pretty time soncuming. You CANNOT import RMU backup save sets this way.
