Migration of dspace handle from old server to a new server

[akuhwa Ver]

Hello Everyone

I have installed dspace version 6.3 running on ubuntu 20.04 LTS. Am trying to backup old dspace server  version 1.8 running on ubuntu 12.04 LTS  but all the dspace backup documentation i used only backup  dspace database. However, i tried using some documentation to configure  dspace handle used on the old server to the new server but none is working for me. Can anybody help me with a recent documentation?

Thank you.
