Confluence 4.3 to the lastest Version
Asked by Michael:

Hello,

on the Online Documentation i got the information that i can perform a upgrade direct to the last Version of Confluence.

So we use the EAR/WAR Installation, that will outdated on the Version 6. How i can handle the change from the lastest war installation to a normal Linux installation.

There are experiences here with a update from 4.3 to the Versions 5.x with out Problems?

All files are stored in a Postgres database that includes the Attachments.

On a test envoiment i have installed the linux Server installer, on the configuration i added a test database with a Dump from the Livesystem.

After i connected the database, but my problem is this database get deleted.

How i can add the dump to the fresh installation?

Thanks

You shouldn't face big issues, however, some plugins might not be supported.

I suggest you to follow the steps below. It should work.

P.S.: I strongly suggest you to try this upgrade in a staging environment to avoid outages.

1 Do a database dump from Confluence

2 Import the database dump to the staging Postgres

3 Copy the \<Confluence-home\> from your production server to the new server

4 Unzip Confluence 5.6.5

5 On the staging Confluence, change the IP address of database connection on the \<Confluence-home\>/confluence.cfg.xml to point to the new Postgres Server (make sure the access between Confluence and Postgres works).

6 Edit the file \<Confluence-install\>/confluence/WEB-INF/classes/confluence-init.properties and change the confluence.home variable to the path where you put the Confluence-Home that you copied before.

7 Start Confluence

8 Change the BaseURL on (Cog Icon \> General Configuration \> Edit) to a different name from your Confluence of production.

9 Make sure the Confluence is running properly (including the plugins)

Remember that we can face issue regarding the Wiki markup to XHTML format conversion which we may need to run the manual upgrade of the content <https://confluence.atlassian.com/display/DOC/Migration+from+Wiki+Markup+to+XHTML-Based+Storage+Format#MigrationfromWikiMarkuptoXHTML-BasedStorageFormat-force_migrationRe-runningthemigration-forcontentthatcompletelyfailedthemigration>. You can get more information about the upgrade through this documentation <https://confluence.atlassian.com/display/DOC/Upgrading+Confluence>.

Also bear in mind that content like external plugins installed would need to be re-installed, since this information is stored inside the database and other related content could be need to first be tracked inside the DB too.

Regards,

Renato Rudnicki

body: The easiest thing to do is move to the "standalone" version of Confluence. Use the [Confluence Standalone setup guide](https://confluence.atlassian.com/display/CONF34/Installing+Confluence+Standalone+on+UNIX+or+Linux) to hook it up to your existing database and the schema upgrade will happen. You don't really need to worry about the X11 configuration stuff. You could export the data to XML, but this really isn't necessary since modern versions of Confluence do an in-place upgrade. Check the upgrade notes for the versions between 4.3 and the one you want to move to. I don't believe you can go directly from 4.3 to the latest version. I believe you need to do at least one interim upgrade, but this will be discussed in the upgrade notes. Obviously, do this on a development system before touching your live production system and be sure you have a good backup of database and the Confluence home directory before upgrading prod. I hope that helps.
