I believe this is the general recommended sequence in most contexts where
the initial incrementals are directed to disk to be later migrated to tape.
That covers most sites.
For those sites with VTLs the situation changes. You are not migrating from
primary storage pools, disk based, to copy pools. The whole issue of
migration dissappears, and you simply back up then do your VTL data to
copypools.
For those sites that have VTLs and high speed tape, they might be granular.
Directing their large database backups, exports, mksysbs, (large files) to
high speed tape directly and directing the remaining backups to the VTL.
Both then copied to copypools.
So, yes, every solution is situation dependent. What hardware you have to
meet your needs and impress others with...........:-).
But it sounded from your initial post that you were in a primary storage
pool on disk situation.

Is there really recomended sequence every TSM Environment should follow?
Or does it depend on your Individual environmental needs?

May I suggest a sequence ?
1- backups nodes
2- backup primary disk pools to tape
3- backup primary tape pool to tape
4- migrate primary disk pool
5- db backup
6- expiration
7- reclaim primary tape pool
8- reclaim copy pool

Objet : [ADSM-L] Migration question
I have a question that I feel a little stupid in asking.
What is the difference between migration and backup primary
(disk) to copy (tape)?
I am working on changing my scheduling up and the recommended
order of steps I was given is:
Backup clients
Migration
Backup primary to copy
Backup db
Expiration
Reclamation
Start all over again
Thanks!
