Upgrading Confluence 3.2.1 32-bit to 4.1.5 64-bit (linux)

We have an old version of Confluence (3.2.1_01 32-bit), and want to move up to 4.1.5.

I understand that we have to upgrade to 3.5 first, but we also want to move to 64-bit.

Is there a recommended way of doing this?... perhaps upgrade through to 4.1.5, then do the 64-bit as a separate upgrade later? Or perhaps there is an alternate (easier?) way of doing this. Correct me if I'm wrong, but I don't see any 64-bit for 3.5 in the available downloads for Linux.

You can upgrade directly to 4.1. Follow this notes:

There is no harm in moving to 64-bit at the same time but it will probably be a bit easier if you do it in 2 steps. Atleast, it will be easier to debug if something goes wrong. I suggest you follow this after the upgrade:

http://confluence.atlassian.com/display/DOC/Migrating+Confluence+Between+Servers

Thanks. I must have misread that document earlier, as I interpreted the following section that it wouldn't be a good idea to import the data, but that rather, the environment should be upgraded.

" Importing an old XML backup file to a new major version (i.e Confluence 3.5 to Confluence 4.0) is not recommended. Please recreate your production instance in a test environment first."

The "bitness" (32 or 64) of Confluence is determined by the edition of Java that you use to run Confluence. You can use a 32-bit Java installation or a 64-bit Java installation to run the same Confluence package - the download from Atlassian is the same, regardless.
