problem with import back up of another project to my engineering workplace
Always while importing structure/object/aspect then ensure that system softwares loaded in the source system & destination systems match else your import will not complete with actual aspect-object else in place you will get GUID.
Always don't import the structure/aspect/objects from full backup may also cause GUID.
So always import separate individual str/aspect/object exported backup.
The problem seems not related to MAC address or IPs of the virtual machine.
THe strange numbers what you see are the GUIDs of the Aspect Objects.
It also depends upon what backup you are trying to import...Whether they are with dependency or without dependency. With dependent backups , all related aspects will also come.
