Hello to all DRK bag holders
I have encrypted wallet.dat from 2014, will I have problems with new DASH v12.1.5 wallet, or I just put wallet.dat in /AppData/Roaming/DashCore/ folder and resync/reindex blockchain?
Thanks

Yeah it'll work like a charm. It's the same blockchain. You'll have to remember your passphrase to make any use of it of course.
Here's an upgrade guide, because I'm nice like that:
