This isn't a complete description of everything I had to do in order to get the latest Friendica working with my existing data, but it shows how I solved some of the more thorny problems.
Table Modifications
- /contact - this is the first one I did, so notes are more explanatory
- /item - this was a large table, and took a lot of time to do the copy
- /gcontact
- /notify
Other Changes
acl_selectors
This SQL:<mysql>SELECT `group`.`id`, `group`.`name`, GROUP_CONCAT(DISTINCT `group_member`.`contact-id` SEPARATOR ',') AS uids FROM `group` INNER JOIN `group_member` ON `group_member`.`gid`=`group`.`id` AND `group_member`.`uid` = `group`.`uid` WHERE NOT `group`.`deleted` AND `group`.`uid` = 1
GROUP BY `group`.`name` ORDER BY `group`.`name` LIMIT 0,100</mysql> ...returned the following error: Expression #1 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'icms-fka.group.id' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by.
Finding where this was being generated required the use of grep:<bash>grep -r "GROUP BY \`group\`.\`name\`" *.php</bash>Note that the -r option doesn't actually seem to work; I had to run this inside the "includes" folder to identify the file -- which turned out to be acl_selectors.php line 505, which I have modified thusly:<mysql>GROUP BY `group`.`name`, `group`.`id`</mysql>
Sticking Point
I finally got stuck -- or, perhaps I should say, decided/realized that the next step was too big of a time-investment -- when trying to figure out where and why this error was happening (Reformatted slightly for readability):

I found where the error was being thrown, but would have to do some significant backtracing just to figure out what was executing the problematic SQL, and/or what was generating it... and, most importantly, why.
