Hi,
a lot will depend on the timescale's you've been given to complete the
migration and the overall amount of volsers that need to be copied.
It may well be that you can get away with just recycling hsm ml2 & backup vols
and not actually migrate anything else as they'll all expire & scratch
naturally over a few weeks.
Not very likely though.
If you are using ca-1 or ca-tlms then they have "copycat" which you could use.
You may even get it gratis if your site has a generic "use any ca product"
licence if not already installed.
Ibm's tape2tape is basically rexx code which will interrogate RMM and build job
decks to copy your volumes, using adrdssu for dfdss vols, gener for flat files
and then idcams delete define to update the catalog entry's with the new
volser(s) for the dataset accordingly.
It is pretty limited and i had to hack it around to cater for other formats
(fdr etc.) when i used it.
N.B the vast majority of tape copying utilities do NOT update hsm metata data
(its internal tape catalog) so are useless for ml2/backups/dumps.
A very good exception is "Tapecopy" shipped by Opentech which caters for hsm
ml2 & backup tapes (not sure on dumps) and which also cross references the back
end tapes to select volsers by b.e.t to minimise thrashing.
There's a lot of products out there to do the job as you can see from the list
in the manual referenced earlier.
Some will work with the tape management system(s) at your site, some wont.
In a nutshell, you pays your money and makes your choice but don't copy stuff
which will expire naturally in a few days/weeks.
Good luck!
Dave
