is this Howto suitable for 3.6.3?
It's what I based my move on, however, I did end up with some extra
hackery to get it to work properly, including extra indexes but that's
something I'm told should be evaluated on a "per DB" basis, and I
suspect ours is nothing like yours.
Rather than using the SQL they provided I just took it straight from the
RT install process.
The mysql2pg script it's self works, however you'll probably need to
update the table names.
I ended up creating a dedicated MySQL slave that I would run the test
migration/upgrade off. This meant that I could stop the replication and
have a static content while testing.
And as Jesse mentions on the Wiki, Binary attachments get messed up, It
took me a while to realize why my database had dropped from 10 Gig to 1 Gig.
Attached is the script I used to fix the attachments. It comes with the
standard "worked for me" disclaimer. I also had a modification in
Attachments_Local.pm to make ContentEncoding, and Content Writable.
# {{{ sub _LocalAccessible
sub _LocalAccessible {
{
Content => { 'read'=>1, 'write' => 1 },
ContentEncoding => { 'read'=>1, 'write' => 1 },
};
}
# }}}
If I understand one of Jesse's earlier messages correctly you could
probably add the following to my script.
{
no warnings qw/redefine/;
use RT::Attachment;
sub RT::Attachment::_LocalAccessible {
{
Content => { 'read'=>1, 'write' => 1 },
ContentEncoding => { 'read'=>1, 'write' => 1 },
};
}
}
