Looks like it also may be influenced by whether you have "Access your Money
data on the web" (also known as "MSN Money synconization") enabled. I had
this turned off in my 04 file before converting it to 05, and then my MSN
Bill Pay account was properly associated with my checking account (rather
than having a new, separate account). If you have it enabled in the 04 file,
I'm not sure my steps below will work. Also, I haven't yet tried re-enabling
the MSN Money sync and so don't know if the accounts will stay associated.

I gave this a shot tonight ... I copied my *.M12 file to an .MNY File and
attempted to convert that (althought the Data is almost 6 weeks old, I
figured it would be a good test). In any case, I also deleted my Temporary
Internet Files before attempting to open the .MNY File (previously the .M12
File). When I opened the .MNY, it told me it would convert the file to Money
2005 and that it had turned off Internet Updating, etc. I went ahead and
stopped using MSN Billpay in Money and attempted to setup an online service.
It sync'd my data with the web, created the new checking account and ...
Unfortunately, I still couldn't merge the new checking with the legacy
checking.

Did I perhaps miss a step?

I upgraded from Money 2004 to Money 2005, converting my 04 file that had MSN
Bill Pay set up as being associated with my checking account. After the
upgrade and conversion, I had an extra separate account for MSN Bill Pay in
addition to my checking account. The MS support pages give instructions to
merge the duplicates accounts, but on attempting this, Money said I had no
duplicate accounts to merge.

I have read on this forum that others have had this same or similar
problems, so I thought I'd share my findings.

It turns out that you have to install Money 2005 AND perform the online
updates that get invoked on starting Money 05 for the first time BEFORE you
convert your 04 file to 05. If you run 05 for the first time and let it open
your 04 file, the conversion is done before the online updates.

I reinstalled 05 and ran it with a new file, allowing the updates to be
installed, then re-ran 05 with my 04 file. I suppose that as long as the
updates have installed, then you could just reopen your backed-up 04 file and
have it converted again.

BTW, MS telephone tech support was very helpful and knew exactly what the
issue was as soon as I described my problem. I wonder why they don't have
this problem in the Money KB?
