I have a question, friends say, delete the local copy of the blockchain, after installing the new version ..... Are they talking about deleting the Blocks "," stateQtum "," database "folders and" banlist.dat "files in the AppData / Roaming / Qtum file, or another step I was unable to update before the hard fork. Due to this incident I am trying to upload my wallet.dat file before the hard Fork to the Qtum wallet version 0.19.1 so I wanted to get some ideas to avoid doing anything wrong.

My last question is I can't see the "deleteblockchaindata -delete the local copy ......" tab in the Restore Wallet option. What can I do so that I can see that option.
