Outlook 2003/XP to Outlook 2007/Vista: lost email sorting rules

[Rudymill]

I copied the Outlook 2003 pst folder to my new computer.
I opened 2007 on the new machine, without setting up email rules.
I used File|ope|Outlook data file, and browsed to the location of the 2003
pst folder and opened it.
My 2003 data appeared.
I used Tools|Account Settings|Data Files and made the 2003 folder the
default folder.
I went to the folder list, right clicked and closed the default 2007 data.
So, I had only the "2003" data list showing.
I created the email account, which defaulted to delivering email to the
"2003" data file.

And now I have none of the 100 or so rules for sorting email.

What did I do wrong?

Thanks in advance.
