Before going on hiatus or whatever you might call it (suspending my hosting account), I made a backup of the entire root directory–I managed to preserve an installation of WordPress. Previous attempts to run that installation after reuploading it have failed, but I have found that it was because of a) .htaccess settings and b) outdated URLs in the SQL (boison.org as opposed to boison.org/old).
So my old WP installation now functions. I just went through and deactivated/deleted all plugins and changed the permalink structure to reflect that of my current installation.
Where should I go from here? I have only a basic understanding of PHP and zero with SQL. I just made a backup of the modified old SQL, so I have room to “play around.”
A couple of thoughts: would it be plausible to remove fields that aren’t in the 2.0 schema from the 1.5 version?
I’m gonna tinker for awhile, ’cause I just confused myself…
