Two different systems with similar "system name".
Planning for a upgrade from 800xA 5.0 to 800xA 5.1, because we are upgrading the hardware. We planned to upgrade the existing domain and join the new systems with new name and load the maintenance backup.
My question is Two different sytems (AS, CS names are unique) with the same "system name" will be a problem for the systems running on 800xa 5.0.
Our plan was to keep the plant live on 800xa 5.0 and add the new systems on different name and install 800xa 5.1 and load the back up, take a short down on the plant and swap the controllers from the old system to new system.
Any valuable answer would be appreciated.

System name is not critical in any way (afaik).
However, System ID (an internal GUID not used visibly) is.
During restore the Config Wizard will ask whether to retain (keep the old) or to generate a new random System ID.
It is important to keep nodes with deviating software versions apart during an upgrade, hence you might select to generate a new ID to make it possible to let 5.0 and 5.1 nodes to coexist briefly on the same network.
Please study the various upgrade paths available in the Upgrade User's guide(s). Don't hesitate to contact your regional ABB Support Center for further advice.
What is the reason to have both systems on the same network? Is it only the domain controller? I guess you have more than one.
Maybe you can add all the new machines to the domain and then split you network. Just make sure that you have at least one domain controller in every network and that you don't change domain settings. Both systems can run independently and you can even keep the GUID if you like.
