Current we have Unity (UM) version 4.2 and Unity(UM) version 5.x run at the same time under same domain and exchange 2003 organization.
The requirement is that we need migrate some part of unity 4.x users to the unity 5.x server.
I tried to use bulk-delete tool,or directly delete the subscriber from unity 4.x, the user can not be imported to unity 5.x server because the user exchange object attributes are still there of the unity 4.x server.
Is there any utility that I can use to delete bulk users at the sametime remove the exchange attributes so that I can bulk import to the new unity server? or even one user by one user? Or do I have to use some AD tool to remove those attributes one by one?
the best way is to move users from 4.x to 5.x is the GSM tool. It deletes the user, cleans the attibutes, then imports it in the 5.x server.
you need to watch the video and read the help files. there is setup and special requirements
