Use the patch files to upgrade.
patch -cl -d [PHPBB DIRECTORY] -p1 < [PATCH NAME]
Also check the hunks which failed. I apply the failed hunks manually.
This will not create problem with the exisiting database or files but if you are not technically sound I advice you to keep a back before doing it.
Have you applied any mod to your phpbb?

install/ directory (which you remove afterwards) and all your database tables etc. will be updated. There shouldn't be any problems, but take a full backup of the database first. Don't forget that you will need to modify your templates - there have been a lot of changes since 2.0.6.
If you really can't rebuild with the new files, than try the patch file available from the phpBB site - but it is harder and usually requires command-line access to the server, and the server must be a Linux/Unix type (not Windows).
Running 2.0.6 is particularly dangerous - there are widely-known exploits on the web that can give anyone full administrative access to your board and significant access to the server itself.
