In past server merges (Windermeer into Arispotle and Cho into Arispotle), in cases of duplicate names the newer character was renamed by adding a "z" to the end of their name. A player whose character was renamed was allowed to request a custom renaming after the fact.
Those are the details as I remember them. My memory might not be entirely correct.
