I suggest that you look at the redMIGRATOR component - there are general instructions how to use it on their website - see the advertisment on the right hand side of this page (redSHOP).

The general steps are (run these steps in this order)

1. Create a brand new, completely empty J! 3.2.1 website; set protostar as the default frontend site template.
2. Configure Joomla SEO on your new J! 3.2.1 website
3. Set English as the default language
4. Install redMigrator component for J1 3.2 on the site J! 3.2 site
5. Install the redMigrator plugin for J! 1.5 on the old J! 1.5 site
6. Configure the plugin on the old site so that your new site can access it
7. Configure the component on your new site so that you can pull the J! 1.5 data across
8. Make a backup of your site (I recommend AkeebaBackup) before you run the migration component on your new site.
9. Make sure that your new site has all the Joomla articles and users from the old J! 1.5 site
10. Export the Kunena tables from the old J! 1.5 site to the new J! 3.2 site
11. Run the Kunena installation procedure to convert the old Kunena data structures to K 3.0.4
12. Fix any category permission issues (remember, J! 1.5 did not use ACLs) so you will have to edit every old Kunena category that you had.
13. Run the Synchronize Users and Recount Statistics tools
14. Test your Kunena forum
15. Think about the Joomla site template you may want to use
16. Set Lithuanian as the default language
17. Install the Kunena Lithuaniuan language pack for K 3.0.4
18. Test that things are working
19. Repeat the test that causes the problems you have in this topic

A lot of work - should take you about 3-4 hours. I hope this helps.

thanks, I will try

I have some quesions.

Make sure that your new site has all the Joomla articles and users from the old J! 1.5 site

you mean, that I should to transfer articles and users using remigration?

Export the Kunena tables from the old J! 1.5 site to the new J! 3.2 site

You mean, that I should to do this manualy from my database? Should I change prefix after?

Run the Kunena installation procedure to convert the old Kunena data structures to K 3.0.4

You mean kunena installation, then data structures will change automaticaly?

And I dont understand when I should to start use remigration component, after 8 point?

And How I should to configure seo?

I left out a lot of details in my earlier message. For example, step 1 - Create a brand new, completely empty J! 3.2.1 website; set protostar as the default frontend site template - takes about 1 hour (or more) to do.

If you have questions about specific things (for example, how to setup Joomla SEO) please start a new topic for each question or search the forum for information about these things. Setting up Joomla SEO is not a Kunena thing; it is a Joomla thing. There is information in the Wiki that will help you to setup Joomla SEO. Setting up Joomla SEO takes about 5 minutes.

10. Export the Kunena tables from the old J! 1.5 site to the new J! 3.2 site
11. Run the Kunena installation procedure to convert the old Kunena data structures to K 3.0.4

I'm afraid, step 11 does not work, if your old table are prefix_fb.
Then you must go the detour over K 2.
github.com/Kunena/Kunena-Forum/issues/2211
The problem with this is that you can not install K 2 on Joomla 3.2
