I sure hope so!

I thought so. I have that info - I did a "scanner -B" on the old bootstrap
tape.

I'll live with that. I'd rather have hassles restoring from tapes made in
that 3 week period, than with any tape made in the last 18 months ....

I know, and accept, that if I need to recover something that was made
inthe last 3 weeks will be problematic.

Right; I need to rename this new server to the old server name. Once I do
that, the old licenses should just come back. If not, I will get EMC to
re-host them to this new host ID.

What I need is the old mm database. I tried to do a restore from a tape
made like 6 months ago. The "scanner -m" told me the client name existed,
so it was renaming the client to ~client. Then, I couldn't find out how to
do the restore from that renamed client - it doesn't show up in the server
client list, it doesn't show up as a source to restore from, etc.
Wanna know what would be ideal for me? If the new server had all the old
client IDs, so that when I did a "scanner -m", it would just add the tape
into the mm database. I'd live with even that. If I had the old client
IDs, I could delete all my current clients, re-install them with the
proper client IDs, and go.
Maybe if I do a mmrecov from the old database, I can print the client IDs
out. Then I can do rename the server back to the name it has today, do an
mmrecov on it's bootstrap, delete all the clients, re-install with the old
client IDs. Would THAT work?
