I'm trying to import all of the users of an instance into a new one via .ldif file, but when i do it, I get this error: `#!ERROR Entry inum=BE58.F665-23B5,ou=people,o=gluu cannot be added because it includes attribute entryUUID which is defined as NO-USER-MODIFICATION in the server schema` I copied a couple users from that list and pasted them into a new .ldif file, I deleted the **entryUUID** attribute from those users and when I try to import them, I got the same error but with the **modifiersName** and the same for **modifyTimestamp**, after I deleted those attributes from the .ldif file, I could finally import users into a new Gluu server instance. The users exported into the .ldif file, come from a Gluu 3.1.5 instance upgraded to the version 4.1. So the questions are: - How important are those attributes from all of my LDAP entries? - Is there any problem if omit those attributes by deleting them from the .ldif file, before use it to import users into a new Gluu 4.2 instance?
