Before doing such a big move, why you didn’t read carefully my dedicated guide or at least ask here first?
http://community.umbrel.com/t/how-to-restore-your-node-wallet/
There’s a section 7 exactly for this where is explaining how to move to another hardware.
There’s NO need to use the seed!
Now you messed up things more.
You will need first to let the node to resync 100% and let electrs to finish the index, then start the restore from seed + backup.
After that you need to wait up to 144 blocks until all your channels will be closed and funds back.
THIS PROCESS TAKE TIME! Have patience please, before doing anything else.
