Question Kunena 2.04 install on Joomla 3.9 ?

As part of a (long overdue I admit) migration from Joomla 1.5 to 3.0 my migration package advises installing Kunena 2.04 on Joomla 3.9.0 before upgrading to 5.x

On a fresh Joomla 3.9.0 installation ( with a new mySQL database) the Kunena 2.04 package seems to install and appears in the component menu, but will not open any configuration pages. Is 2.04 not compatible with Joomla 3.9 ?

All the basic Joomla tables have migrated OK. I've tried with the package installation first and then kunena tables and also tables to an 'empty' Joomla and then installation.

A Kunena 5 installation works fine but cannot read any migrated earlier fb- tables.

To make life even more difficult I also can't get the original Joomla 1.5 to upgrade Kunena from 1.5.13 to 2.04 either (as suggested) though that seems to be more of a Joomla installation problem and directory permissions to be fair.

You can't install Kunena 2.0.4 on Joomla 3.9, it's not compatible. But it works also with Kunena 4.0.12 github.com/Kunena/Kunena-Forum/releases/tag/4.0.12
Afterwards you can upgrade to K5.1

Thanks for that .

My major problem has now been sorted. I needed to upgrade from Joomla 1.5.n to 1.5.25 before I could upgrade to Kunena 2.04 on the original site. A folder write error was preventing it. Seems my hosting provider changed the structure of customer folders some time after this Joomla installation was done. Re-setting the path to tmp allowed that to proceed.

I'll try Kunena 4.012 and hope the 2.04 table structure is compatible to migrate to that.

If there are problems, you can go another way, when your migration tool did not change the Joomla user IDs. The same user IDs are important, so that the users can be assigned to the right Kunena messages.

1. Export all Kunena tables from the old Kunena database and import this tables in the new installation.
2. Adjust the prefix if it's not the same
3. Install Kunena 4.0.12 (Kunena recognices the old tables and migrated this tables to the new structure)

Hint: Joomla 1.5 has another user management as Joomla 3.9. Therefore you must after a migration adjust all category permissions manually, otherwise users have no access and can't see the categories.

Thanks. I've got a Joomla 3.9.0/Kunena 4.0.12 site sort of working (all tables migrated first then Kunena installation). The user names appear to have synchronised OK (well my Supersuser and 'normal one have anyway) but I still need to copy across avatar .jpgs. Good heads up about category permissions, I will check. Getting there slowly though.

Mostly sorted. The category permissions gotcha hint was much appreciated - thanks!

Some detective work and ingenuity was required to work out where to copy the old attachments to , which for my installation is now:
<site>/media/kunena/attachments/legacy/images/

Still trying to do the same for avatars but not bothered if I can't.

Only one real glitch in that user IDS 1100 and 1101 seem to have got mixed up so posts attributed to the wrong user name. I think I can sort that by hitting the tables direct but is there an entity relationship or schema map for Kunena 4 on-line anywhere? I can try to reverse engineer it but a crib sheet would be handy.

Next up UddeIM - I may be some time...
