Solved How to migrate from K 1.7 on J! 1.5 to K 3.0 on J! 3.x?

Hello Users,

I have a little problem with a migration from Kunena 1.7.1 to 3.0.6.
(Okay, I should have updatet it a few "years" ago)

Now I run the 3.3.3 Joomla with the 3.0.6 Kunena.
I want to import my old categories and the topics of the old forum.

How can I do it? Just tried to "import" the old database
(from Joomla 1.5.23) but it didn´t work.
I think there are some basic database issues.

Can you give me a tip?

Thanks

check your prefix on your database.

The Prefix differs.

Old installation: jos
New installation: w3826

I tried to change it manually (in the exported file from the old installation but it didn`t work). How do I change it correctly?

Now I run the 3.3.3 Joomla with the 3.0.6 Kunena.

You have installed already Kunena 3.0.6?
If you use phpMyAdmin then proceed as follows:

1. create a backup of your database
2. deinstall Kunena 3.0.6
3. remove all w3826_kunena tables from your database
4. import all jos_kunena tables in your database
5. mark all jos_kunena tables
6. scroll down and chose in the dropdown menu "Replace table prefix"
7. from
jos_
to
w3826_
8. install Kunena 3.0.6

Thanks @Rich.
