Efficient way to migrate a pruned node I would like to know what are the step to succefully migrate a pruned node.

I have a Raspnode (rPi2B+) and it is so slow that it doesnt seem to sync the blockchain after several days...

I want to sync the node that I have in my laptop and move it (pruned) to the Raspnode.

I have copy and paste all the files in the .bitcoin folder and when I execute the bitcoind -daemon command the follow is in the debug.log file

Do you want to rebuild the block database now?

The idea is to sync the node in my laptop and then maintain the syncing (and pruning) on the rapsberry pi because I cant run the node all the time in my laptop.
Copying .bitcoin folder should work. Make sure bitcoind is not running (try ps -ef | grep bitcoin)  before you attempt to copy. Also make sure bitcoin.conf is same in both places

Also, change the bitcoin.conf file with the new datadir , rpcuser and rpcpassword
