MS Exchange certificates and ROMs

[lip]

Hi,
My old touch died and during the period of getting a new one, our company changed their exchange servers or something.
Anyway, the IT guy put some exchange certificates on the phone...if I upgrade the ROM, can I just copy over these certificates?

Thanks.

Mine is set up where you get prompted to install a certificate anytime you try to add the account for the first time.
