I am trying to import data from RT 3.8.4 into RT 4.2.10.
I first tried to update in place, but that failed. [Ancient version

I next did a clean install on SUSE (12.2, 64bit), which worked.

The upgrade-articles is the succeeding step I think you are thinking of.
While I did not do “make dropdb”, I did “drop database rt4” in mysql,
followed by “create database rt4”, “use rt4”, and "source ".
This let the RT4 tools access the old data, allowing the upgrade-database
Sofar its OK. Your RT instance is usable from here.
The serializer exported the data to a neutral xml format. I then reset
the database back to the clean-install’s version I had previously saved.
This loaded the old data into the new database, but changed the ticket numbers.

tells you to do this.
When the initial upgrade-in-place failed, I did not trust the database
was properly updated. So I used the export/import to make sure I had
Following your suggestion of not doing that, the data seems OK, although
I still have lingering doubts. Especially as I get these messages in the

I went into mysql to change the existing “RT::FM::Article” entries into
"RT::Article", as this seems to be what it was doing. I don’t know if
it needed to make any other changes after this point.
