If the server is the same brand, it should be OK. You don’t really need to move the backplane – just the drives and controller. If you are trying to mount the physical cage into a new box, you may not have success. In this case, you may be better off doing a data migration.
If you can move the drives:
1. back up your data TWICE
2. make sure you have a backuut plan
3. back up your data TWICE
4. If you are using Windows, you may have problems with the new motherboard resouces if the servers are drastically different.
