12Upgrading and downgrading
13=========================
14
15How to Upgrade
16--------------
17
18If you are running an older version, shut it down. Wait until it has completely
19shut down (which might take a few minutes for older versions), then run the
20installer (on Windows) or just copy over /Applications/Bitcoin-Qt (on Mac) or
21bitcoind/bitcoin-qt (on Linux).
22
23Downgrade warning
24------------------
25
26Because release 0.10.0 and later makes use of headers-first synchronization and
27parallel block download (see further), the block files and databases are not
28backwards-compatible with pre-0.10 versions of Bitcoin Core or other software:
29
30* Blocks will be stored on disk out of order (in the order they are
31received, really), which makes it incompatible with some tools or
32other programs. Reindexing using earlier versions will also not work
33anymore as a result of this.
34
35* The block index database will now hold headers for which no block is
36stored on disk, which earlier versions won't support.
37
38If you want to be able to downgrade smoothly, make a backup of your entire data
39directory. Without this your node will need start syncing (or importing from
40bootstrap.dat) anew afterwards. It is possible that the data from a completely
41synchronised 0.10 node may be usable in older versions as-is, but this is not
42supported and may break as soon as the older version attempts to reindex.
43
44This does not affect wallet forward or backward compatibility.
