Fromdate/Todate is actually your friend.
Look at the backups you have for this server, and how far back they go.
Try an export with FROMDATE/TODATE that specifies, say, Jan 1- Jan 5 (with
merge=yes).
See how long it runs.
If it doesn't run too long, try more days in the interval the next time.
By doing that repetitively, you can get your exports down to something that
doesn't run so long you have to cancel it.
Rinse and repeat with additional date ranges until you've brought over
everything you need.
With merge =yes, what you get in the target filespace is whatever your mgmt.
class specifies on the target server.
If you bring over more versions than your target mgmt. class allows, they
immediately roll off. If you accidentally run the same import twice, the
imported backups replace existing ones, without forcing a version rolloff. (It
works like you want it to).
I've done this before and it works like a champ!

Subject: [ADSM-L] How does EXPORT MERGEFILESPACES really work
Is there a document that explains the logic behind EXPORT NODE, in particular
the MERGEFILESPACES option, when it comes to merging into existing filespaces
and TDP data? How does it select what to export (active first? inactive?,
FIFO? LIFO?)
I am trying to move large nodes (>6TB each - 8-nodes to move) from an old
5.5 server to my newest 6.2.2.x server. Since the node daily backups (DOMINO
TDP) can not be stopped while the move is going on, I can't move this much data
within 24-hours (after running for 3-days, I killed it).
So, I moved the definitions and starting clean will full backups (we run full
selective backups bi-weekly, anyway - don't ask......). However, the existing
data must be retained/moved from the old TSM server.
Since it will take multiple days to move, what happens with what is targeted to
move (inactives plus the active) when new backups are occurring, expires are
running, etc?
Since it is TDP data, I can't separate by filespace. Not sure if the
FROMDATE/TIME would be of much value since some of the daily incrementals run
for >24-hours.
Thoughts? Suggestions?
