Yes as far as I know but to be safe here is how I did it.

• I deleted everything except the wallet.dat file (in the data directory)
• On the first PC I downloaded the entire blockchain from scratch
• On subsequent PC's I deleted everything except the wallet.date file and then copied the blocks & chainstate folders from that first PC's download
• Before I started the HOdl wallet for the first time I added -zapwallettxes=1 to the shortcut icon path

To add a bit more I'm not sure the -zapwallettxes was completely necessary but it served to clear those failed transactions from the transaction table. After the above steps my current block matched the block explorer and I'm able to mine, HOdl, send and receive with no more issues.

In the data directory I wasn't sure about the necessity of deleting the database folder, db text doc and peers.dat but I went ahead and deleted them to force the HOdl wallet to rebuild them from scratch. I had a concern there could be some issue stemming from keeping the database and I also had some concern if the peers.dat file would try to reconnect me to a Version 2 node that was connected at the Version 3 fork and never disconnected since the fork if that makes any sense.
