Migration of clients from Solaris master server to new linux master server with backup images
Hi Team,
I have an activity to perform for my client and need your suggestions. The activity is:
Existing setup:
Master - solaris 11 [standalone, means non-clustered], NB Version - 7.7
Another site:
Master: Linx 6 [VCS clustered], NB Version - 7.7
I have to migrate certain clients from Existing setup to another site, i.e. move clients which are currently being backed up by Solaris master server, to new master server i.e. Linux
- We want to move the old backups as well
-The old backups includes, windows, linux, solaris clients with Vmware, Oracle, MS-SQL, Filesystem backups
Here is my plan:
1) Isolate the clients and policy list
2) Determine all backup images with backup and expiry date
3) Determine the list of medias used in the backups of all these clients
4) Move the tapes to new tape library and placed them in SAFE volume pool
5) Run phase 1 on all these tapes and run phase 2 import for images determined in Step 2
6) Run bpimagelist -recalculate against all these images with the date as expiry date we find in Step 2
7) Modify the bp.conf or registry for SERVER entries and populate the new servers
8) Modify the scripts for oracle & SQL DB backups
9) RUn some test restores to test if everything is ok
10) Disable the policies in Solaris master server
My concerns are with the DB backups and vmware backups. With the phase 1 and phase 2 imports are enough for DB backups?
Because, I beleive RMAN also keeps the information about backup media server or backup server, which will change now. Any extra steps required?
Thanks for your assistance and time.
Hi
I"m no Oracle expert but as far as I can see it should not matter. Oracle will ask RMAN catalog for the backup image name/tag, as shown below. There is no reference to the Master in RMAN catalog.
