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