Once the SQL db is migrated create a new DSN (that looks like the old MF20.dsn on the servers Then run DSMAINT CONFIG Run /? Toi get all the parameters but you have to path to the DSN and give it the SQL username and password for the DB, the registry will now be changed to point to that new DSN and all will be happy in citrix land.

Do you know an easy and harmless way to tell Citrix boxes to connect to the different SQL Server? there are new server names and ip addresses. our dba is a smart cookie - the sql end is not our concern - it is the existing production MF farm that needs to be working seamlessly when we do the final power off of the old sql server. can someone point me to concise instructions on how to do what is needed on each MF server in the farm? all documents I have found in various kb's / forums are incomplete (or contain erroneous information) thanks in advance Jeff
