Hi Dojo,
We have several DMAs (part of the cluster) in a domain that will soon be retired. The agents (the servers hosting the agents, to be precise) will be joined to another domain used in another part of the cluster.
Is there anything that we need to configure in DataMiner to perform the change? Or will changing the domain on an underlying server not cause any harm to a DataMiner agent?
I know from Dataminer LDAP & MSSQL Active Directory Update Queries - DataMiner Dojo that we need to update user accounts - remove users in the old domain, ensure there are some local users available while the domains are switched, and add users from the new domain afterwards. Is there anything else we should expect in terms of impact on DataMiner?
Hi Alexander,
DataMiner itself normally doesn't really use or rely on the domain. So, if you switch the OS to another domain, I cannot really think of any impact this might have on DataMiner. Everything should continue to run in the new domain as it did in the old domain...
Of course, like you mention, the users configured in the DataMiner system which are linked to domain users, will need to be reconfigured.
To be complete, there is actually one situation you might need to reconfigure something, and that's when custom connection strings were configured (Editing the connection string between two DataMiner Agents | DataMiner Docs). Typically, the DMAs in a cluster will be able to communicate with each other because they are on the same domain, but if that is not the case, you can specify connection strings to tell each DMA how it can connect to another DMA and which user it must use to authenticate. As I mentioned, if all DMAs are in the same domain, that should be no problem because DataMiner is running as System account, but if such connection strings would be configured and a domain user is being used, this user might need to be updated to a new user on the new domain. But I believe this is probably more of a corner case.
