We have Groupwise 2014r2 with roughly 175 users. The system has been in use since WordPerfect office days. I've been moving users individually from the original system PO on Windows (moved from Netware) to new post offices on SLES. Some users have had blackberry phones, which moved to iPhone. Before moving users I run gwcheck until the log is error free.
Many of of my moves result in duplicate address books, most often the personal address book, once in a while the frequent contact book. When it happens the original address book is renamed with  after the name. This always makes it complicated for the uses and usually requires extra effort on the part of our sysadmin. Anyone seen anything similar?
