We have three Organization tenents, Dev, Test and Live. All hosted on premise (CRM 2011. [5.0.9690.4376] [DB 5.0.9690.4376]).
Because the way dialogs uses GUIDs to refference record in Lookup, we aim to maintain GUIDs for static records same across all three tenents.
While all other entities are working fine, I am failing to import USERS and also maintain their GUIDS. I am using Export/Import to get the data from Master tenent (Dev) in to the Test and Live tenents. It is very similar to what 'configuration migration tool' does in CRM 2013.
Issue I am facing is that in all other entities I can see the Guid field and hence I map it during the import wizard but no such field shows up in SystemUser entity while running import wizards. For example, with Account, I will export a Account, amend CSV file and import it in the target tenant. When I do this, I map AccountId (from target) to the Account of source and as a result this account's AccountId will be same both in source and target.
At this point, I am about to give up trying but that will cause all dialogs that uses User lookup will fail.
Thank you for your help,
