You may encounter an issue with trying to release reports to your AX environment when you move databases between environments. The error you might receive, during the report release, is Publish_AXReport: The user or group name ‘xxx’ is not recognized
Even though everything is setup correctly in your AX environment, the error is caused by having additional records in the table SysServerSessions. If from SQL you review the data in this table you should notice that you have records that point to old servers/instances. You need to delete all the records that are not relevant to your current environment. Once done you should be able to deploy reports with getting the user or group name error.
