Just to be sure:
I upgraded the firmware of a 4100 to the compatible version of the current version on the 300, using the 300 release notes.
the 4100 has an existing zoneset which needs to be kept. I now want to connect the 300 to the 4100 to merge the fabrics and then finally disconnect the 4100 to get rid of them.
Just to be sure, what things do I need to do when merging the fabrics?
is a different domain id and zoneclear enough on the 300 before connecting?

It depends, is they b300 brand new/never been used before?
For a merge to be succesfull at least
-domain id's must be different
-zoneing must be 100% identical or new switch has to have a empty zoneset
-fabric.ops parameters mus be identical
But you can try to merge the two.
If the merge fails it states the reason in the eventlog as to why it failed

Thanks, the fabric merge succeeded perfecly and the hosts connected to the 4100's are now succesfully zoned to the storage array connected to the 300. at this point, the 300 is subordinate and the 4100 is principle. when I remove the 4100 at a later stadium, do I need to make sure the 300 is principle and keep the zoneset, or don't I need to care about that and everything keeps working?

You can have it either way.
If you worry about it you can force the principal role by means of the fabricprincipal command, use help fabricprincipal for syntax and explanation.
If you do nothing the 300 will take the principal role, because it the only switch left, after the 4100 has been disconnected
