Information in this document applies to any platform.
We are running into huge performance issue doing imsbackup / imsrestore hosts with Messaging Server (MS) 8.0.1.
When migrating (rehostuser) from one MS 8.x store to another MS 8.x store, the imsrestore is taking more than five hours!
Whereas, doing the same migration from:
MS 6.3 to 7.x
MS 6.3 to MS 8.x
MS 7.x to MS 8.x
normally takes anywhere between 10 to 20 minutes.
The performance is especially bad on particular mailboxes which may have 20,000 to 40,000 folders.
- Issue only occurs when doing migrations between MS8 stores (MS 8 to MS 8 migration)
- MS8 to MS8 migration taking 5hrs+ while MS7 to MS8 takes 10-20mins
(Also have log of MS6.3 -> MS8 which only took ~17mins)
- No issues with migrations that went from 6.3 -> 126.96.36.199.0 -> 8.0.1
