Upgrade problems (2.9.2 > 3.5.17)

Ruben Demey

Hi,

I had a lot of MySQL related problems when trying to perform an upgrade from 2.9.2 to 3.5.17. Managed to resolve most of them using guides from Confluence documentation:

1. I changed transaction isolation as described here:

https://confluence.atlassian.com/display/CONFKB/Confluence+Does+Not+Start+with+%27MySQL+session+isolation+level+%27REPEATABLE-READ%27+is+no+longer+supported%27+Message

2. Altered DB engine to InnoDb as described here:

https://confluence.atlassian.com/pages/viewpage.action?pageId=192872609

3. Changed JDBC connection settings and table character sets and collations as described here:

https://confluence.atlassian.com/display/DOC/Configuring+Database+Character+Encoding

4. Modified my.cnf to achieve this:

Server characterset: utf8

Db characterset: utf8

Client characterset: utf8

Conn. characterset: utf8

But now I'm stuck with this one:

LATEST FOREIGN KEY ERROR

------------------------

120914 11:07:45 Error in foreign key constraint creation for table `confluence`..

A foreign key constraint of name `confluence/FKD8C8D8A5117D5FDA`

already exists. (Note that internally InnoDB adds 'databasename/'

in front of the user-defined constraint name).

Note that InnoDB's FOREIGN KEY system tables store

constraint names as case-insensitive, with the

MySQL standard latin1_swedish_ci collation. If you

create tables or databases whose names differ only in

the character case, then collisions in constraint

names can occur. Workaround: name your constraints

explicitly with unique names.

Any help would be appreciated.

Regards,

Igor

So, the answer to my problem was to manualy remove 3 foreign key constrains from the database before performing the upgrade (those 3 the upgrade was complaining about).

After that the upgrade from 2.9.2 to 3.5.17 went fine.

Hello Igor,

Firstly, can you confirm you're trying to upgrade Confluence from the 2.9.2 straight to 3.5.17? If so, this will likely fail (as you can see already) since it's a pretty big jump and there were a lot of database changes introduced in recent Confluence versions.

I suggest you use an intermediary step before going to 3.5.*. In this case it would be 2.9.2 > 3.0 (introduced new license version) > 3.5.17.

Can you try that out and let us know the results?

Ruben Demey

Hi Alyson,

I tried to do what you suggested (with version 3.0.2). Unfortunately, the results were very similar: http://pastie.org/4738194
