always include a copy of error message.
Copy blk* and database/* nu.conf . Permission must be set to 600. You don’t have to copy addr.dat.
Don’t copy debu.log and db.log. If you start with no wallet, new empty wallets will be generated and things usually go faster and more smoothly. Once everything is sync’ed, copy your wallet with coins to the directory. The data bases and wallet will be sync’ed again quickly.
