StoppingEV before Exchange DB migration & Which queue to check ?

[John_Santana]

Hi All,

Can anyone here please assist me in checking which MSMQ queue section do I need to check in EV v10 to make sure that the Exchange Server 2010 database migration to new database name & location is not impacting the EV archiving ?

Do I need to stop all EV archive task except the EV Exchange journaling to ensure that user can still access to their archived email or not corrupted ?

you could put EV in backup mode if you wanted to. archiving is per server, not per database so i dont think it would be much of an impact.

[John_Santana]

ok, so if I put the EV in backup mode, does it going to stop the current email archiving process / stil lrunning ?

[AndrewB]

nothing gets archived while EV is in backup mode but everything is still accessible by the users and for ediscovery. think of it as read-only mode.

[John_Santana]

ok, but in terms of user accessibility and EV overall health, shall I just stop the EV archiving task or is it possible just to right click and set as backup mode before the Exchange mailbox DB migration ?

[AndrewB]

if it isnt critical for users to get to their stuff or for ediscovery, i would stop the task.

[John_Santana]

ok, so which task to be stopped here ?

The mailbox provisioning or the mailbox archiving ?

You could just stop the Task Controller Service and it will stop all the tasks.  When you are done just restart it and the tasks should start back up as well.

If you want folks to still have access to their stuff I think you should just put the EV servers in backup mode.

Hello John,

What I would do:

Verify you have the SynchInMigrationMode registry key set (just to be sure)

On all mail-archiving tasks, place the checkmark in the 'report mode' checkbox.

Restart each task.

Look at MSMQ, verify your Storage queue, and preferably all other queues are empty. If the A5 contains items, that is ok.

When empty, set backup mode on the stores and indexes.

Move database

Run provisioning. Verify Database shows in target tab of the mbx archiving task

Sync mailboxes (from sync tab on mailbox task) (you can check MSMQ, if that is empty again, mailboxes are synced, or check eventlog).

uncheck reportmode on tasks, restart.

Monitor, and test

Clear backupmode on stores and indexes.

how'd it go?
