Question [Solved] Migration phpbb3 to Kunena 5.0.14

It's better, I'm making progress. I found a lot of my problems.
Downloading the database, I was missing 10 tables including the users table...
Now, I can run the script and I want to migrate the database. But there's still 2 errors (I didn't realize the Red system errors):
line 984: Lookup Error - MySQL Database Error: Unknown column 'msn' in 'field list'
line 1140: Lookup Error - MySQL Database Error: Duplicate entry 'web-media' for key 'aliases'

Once migrated, I go to the site to test. The statistics appear, but not the topics or messages. I want to go in the administration of joomla, my IDs and passwords no longer work.
Look in the users table, all users are present, but most Super Admin, or Admin, mixerp which was to create...
I think I'll put the creation command to to Amin, mixerp at the end...

I got the identical errors, but they will not matter anything. The forum is not visible because you have to configure categories in administration, so they will be visible. Add Categories of your forum. You must do that, so they become visible. You have to change settings for each category of the forum. I had only a top section and all other categories under it. I think you will fix this. You will loose PM of phpBB3, but you can later install UddeIM as PM.

Note: log in in administration with username: mixerp and password secret.

When in admin you can change back to your nomal superuser.

You have also to do this:
Copy your attachments from phpBB to:

media/kunena/attachments/migrated/

They have no image extension, so from a command window in that folder make the command:

ren *.* *.jpg

Then they all become jpg-files.

Copy avatars from phpBB3 to

media/kunena/gallery

I copied members personal avatars to:

media/kunena/gallery/members

I did that as avatars settings are lost in the conversion and personal avatars, must be possible to choose for members.

Then copy your rank images from phpBB3 to Kunena.

media/kunena/ranks

Then copy smilies from phpBB3 to Kunena:

media/kunena/emoticons

In Kunena administration check ranks and smilies. If you are going to use phpBB 3 smilies you have to add them in smilies administration.

Thank you so much for everything.
I finally managed to migrate my database and enter the back office of my site.
I also reactivate the categories that were hidden. They appear now. More than a few tweaks to do.
After the migration, all visible posts are written in raw HTML and we see the code. Even by changing the Joomla editor, nothing changes. I think it comes from migration. All the codes appear instead of loading the format.

For me certain html tags appeared after conversion like smilies, youtube tags, certain links tags, but it does not disturb me much most people dont read old posts. What you can fix are the smilies html tags, but you have to make changes in the conversion script for this. Youtube-links and links tags are impossible to remove, because they are variable. The script does not remove such things. What happen when you make a new post. Note that in Kunena Admin, Tools, Diagnostics certain errors can be fixed. Also Re: errors.

Thanks you for your explications. I have succeeded in migration.

Next step (just for me), I must modify the teamplate... and it's been ok...
