Hi jciconsult,

Thanks again for your very quick answer!

There are a lot of viewers at this topic so I think I am not the only one who is busy with Migration to total new CB sites on Joomla 1.6/1.7

I cannot wait longer for 1.7. My site is Joomla 1.5.20-Legacy / CB 1.2.3 and full under attack from hackers. But the step from 1.6 to 1.7 is not that big, just like going from 1.5.20 to 1.5.21 it what they write on

Just for all the comming updaters, I will give some more information bellow about doing an update by export/import tables.

NOTE: If you doesn’t mind that all users get a new user_id you should of course use CBJuice2 as that is cleaner and give some nice extra options. But in my case every user has told all his relations to donate money on his user_id number and the backend bookkeeping is totally automated. If I should use CBJuice2 another user wil get the user_id number from somebody else and people think they donate person A but then person B is getting the money on his charity raising target.

Beside the earlier in this topic mentioned tables jos_user and jos_comprofiler you have to take care for the ACL.

In Joomla 1.5 this was done by acl_aro tables in the DB. These functionality from jos_core_acl_aro from Joomla 1.5 seems to me to been taken over by the much simpeler jos_user_usergroup_map in Joomla 1.6. This table has only 2 values, the user_id and the coresponding group_id.

1= Public
8=Super Users
So, you have to create for all CB users a record with his user_id with the value 2 as all CB-users are Registered users.

You can consider also import jos_sessions which have all the number of hits info etc. about the users but if you don’t use that, like me, you can skip that import to clean-up the new DB.

This all is beside additional plugins like newsletters etc. (which I doubt JBjuice2 will take care for) that can also have user-id’s stored in they own tables.

I will give it a try. No guts, no glory If you consider to do the same, give me a call after a few weeks and I can tell you how it went.

By the way have a nice vacation and If you are in the middle of The Netherlands, you can also call me for a cup of coffe at my home;-)

Have a nice day,
