https://github.com/bitcoin/bitcoin/issuesUpgrading 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), then run the
installer (on Windows) or just copy over /Applications/Bitcoin-Qt (on Mac) or
bitcoind/bitcoin-qt (on Linux).
If you are upgrading from version 0.7.2 or earlier, the first time you run
0.9.3 your blockchain files will be re-indexed, which will take anywhere from
30 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 0.9.x and then decide to switch back to a
0.8.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 0.8.x release on a 0.9 wallet it will rescan
the blockchain for missing spent coins, which will take a long time (tens
of minutes on a typical machine).
