Upgrading and downgrading

How to Upgrade

If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), uninstall all earlier versions of Verium, then run the installer.

We recommand before any upgrade that you backup your wallet.

If you are upgrading from version 1.2 or earlier, the first time you run 1.3.1 your blockchain files will be re-indexed, which will take anywhere from 5 minutes to several hours, depending on the speed of your machine.

Downgrading warnings

The 'chainstate' for this release is not always compatible with previous releases, so if you run 1.3.x and then decide to switch back to a 1.2.x release you might get a blockchain validation error when starting the old release (due to 'pruned outputs' being omitted from the index of unspent transaction outputs).

Running the old release with the -reindex option will rebuild the chainstate data structures and correct the problem.

Also, the first time you run a 1.2.x release on a 1.3.x wallet it will rescan the blockchain for missing spent coins, which will take a long time (tens of minutes on a typical machine).
