How can i upgrade confluence from 5.0 to 5.6.5

[Administrateur Confluence]

Hello,

I installed Confluence 5.0 - EAR / WAR (ZIP Archive), I want to upgrade it to 5.6.5.
Can you please provide me the procedure to do this migration.

Thank you.

Can I go directly from 5.0 to 5.6.5 without going through the 5.1,5.2, ...

In theory, yes. But the upgrade routines assume a standard Confluence with no tweaks, and there aren't really a lot of those around! In practice: Read the release notes for each big version (5.1, 5.2, 5.3 etc) in case there's anything that might affect you. Then do the same for ALL user-installed plugins you've got and want to keep. Then, set up a test system and test it!

You can also give a try to the manual procedure of the upgrade, once you have the upgrade path in mind:

(!) Before jumping to the standard procedures form a upgrade, we suggest the users to check the plugin compatibility with the next versions :https://confluence.atlassian.com/display/UPM/Checking+Add-on+Compatibility+with+Application+Updates. With that in mind, we can start the upgrade process by following the standard procedures:

1. Go to atlassian.com and download Confluence: https://www.atlassian.com/software/confluence/download-archives 
2. Extract the zip/tar.gz file of the latest version of Confluence on the place you choose. ( I highly suggest that you create a folder call: Confluence 'new version') and inside of this folder extract the install folder.
3. Into the extracted folder, open the file confluence-init.properties, which is located at Confluence install directory\confluence\web-inf\classes and edit the line: confluence.home=/usr/local/confluence/home to point to the path where is your old home folder of your *Confluence current version*.
4. Now start Confluence through your new installation folder

Hope it helps ya!

Cheers,
