Instructions

Before anything, backup your wallet.dat (File > Backup Wallet), ideally in a different drive.

When upgrading to a version prior to v.013.4.1, it would prompt you to do a one time reindex to enable txindex=1. This will take about an hour.

If upgrading from v0.13.4.1, no reindex is required. If you have a Znode started, if you start and stop the daemon quickly within an hour, a znode start is not required though always good to double check and verify the start status.

If you are stuck when upgrading to this version, make sure to go into your Zcoin data directory and delete peers.dat and banlist.dat then do a reindex.

Read this guide on how to reindex.

Safety Precautions

Before doing any Zerocoin mints or spend, make sure to do File>Backup your wallet.dat and save in separate location so you can restore in the case a mint/spend does not confirm.
