Glad I could help.
For migration from site to site you also can use this. It's even easier.
- Export this tables from the old site:
jos_users ; Jos_core_acl_aro ; Jos_core_acl_groups_aro_map
- Delete in the new site the same tables.
- Import the exported tables into the new site
Jomsocial
- Export all the jos_community* tables from the old site:
- Delete in the new site the same tables.
- Import the exported tables into the new site
- Copy the following folders from the old site to the new site:
/images/avatar ; /images/groupphotos ; /images/origionalphotos ; /images/origionalvideos ; /images/photos ; /images/videos
Do the same with all the kunena tables.
Be sure you have the same versions on both sites, otherwise first update to a newer version. Also sometimes extensions have some problems with the database. In that case, just import all the tables and run again an installation of Kunena and Jomsocial. Your settings will not be overwritten, but sometimes new data entries will be made.
Older extensions can be a problem yes. There are some extension to make your own modules/plugins. I want to try one of these days if I can update an older version with this. It may be possible to make an empty module, copy the php, scripts etc in this module. Hopefully it will work then in a newer version. But...it just an idea..if it will work...time will tell
