transfer junk mail settings to new pst

i need to transfer the junk mail settings from one inbox to the other inbox. they are 2 different psts. the one pst had many years of building a strong junk mail filter. (rigght click and select junk mail). new pst gets all emails forwarded from old pst email addy, so has no rules and is getting all those junks since it is not server side junk filter.
