I can't find anything about this, but surely I am not the first who wants to do this...
we have joomla 1.0.15 running with nBill V1.2_10
what I want to do is migrate joomla to 1.5.21 (and eventually upgrade nBill to 2.x)
is there a migration tool for nBill data?
or - how do I make sure my nBill gets migrated to the new joomal installation?
and... should I update nBill to 2.x FIRST, then migrate Joomla, or the other way around?
domain will remain the same, I will probably setup the new joomla in a subdirectory first, do the migration, test, then move it up one level to the root, as I did with other sites.
