If you are staying on the same version of MIMS, do not have significant customizations, and are not changing any business functionality, the conversion should be relatively minor. Depending on how experienced your AIX admins are, this could easily be done in a couple of weeks (with most of this time spend in data validation).
If you need to bring in hired AIX/Webshpere/Tuxedo experience (from Mincom or elsewhere), or have extensive customizations, it could take months and lots of people.
