800xA system Name Change
Is there any procedure for changing the running 800xA system name..? 800xA 6.1
Use caution - maintain backups to be able to revert in case something goes wrong.
Just because you can edit the system's name (and description) on the Domain object does not mean everything will work properly after a change.
E.g. up to version 5.0, Engineering Studio would fail after a name change since it was using the system name to build the path to its MS SQL Desktop Engine database directory on disk. After the rename the Engineering Base service would fail.
System 800xA has a large number of optional features (connectivities, application servers, historians, etc). To be certain a name change will succeed without causing trouble, you need a "Go" from each of the system extensions you have installed. For a fully fledged system you might have to spawn 10-15 support cases with your regional ABB support center for which they will have to further escalate to an almost equal number of R&D centers.
