Uh-oh, they just told me we have to migrate all our Windows MQ servers from an NT-4 domain to a Win2000 Active Directory. By 12-01-2005.
The servers in questions are Win2000 SP4. MQ 5.3.0.8, and for the ones with WB-IMB, 5.0.4. And to make it even more fun, many of them are Microsoft hardware clustered (MSCS).
Has anyone done something like this?
For a plain MQ server (not hardware clustered), I think all we need to do is stop MQ, give it to the server guys to migrate it, and when we get it back, use dcomcnfg to tell MQ not to use MUSR_MQADMIN anymore, but rather the domain ID we have set up for them in the domain mqm group. Note that we already have other Win2000 MQ servers in that AD domain we are migrating to, and they work just fine using the domain ID.
For MSCS servers, they are saying they need to uninstall reinstall Cluster Administrator, meaning we would have to move the QM files from SAN back to local disk, stop MQ, let them do their server thing, use dcomcnfg again to switch the ID MQ uses, move it back out to the SAN, and start up MQ. ???
What about for WB-IMB? Anything special there with a migration to Active directory if it is running on MSCS?
Is this task documented anywhere?

When we started we were already on Win2k, so I have not migrated from NT to 2k. But here my 2 cents.

Personally speaking I would change the dcomcnfg even before the migration to AD. AFAIK, Windows is checking the log in only once you use it, and as your Server guys will most likely reboot the server anyway, you could potentially save some time.

Not sure on that. But wouldn't it be enough if you register the ressource type and the queue manager again in the cluster after the migration? I mean they don't touch your shared disk and so on?! So I don't think anything will happen to them. If you decide to try it, let me know the result  |
