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), 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).

||
