I just did mine a couple weeks ago - still waiting on approval from Manila.
The main form is the same, it is a multipurpose form (Consolidated General Application Form). The same stuff is the NBI clearance, copies of passport, and letter of request (slightly reworded). The main difference was that we did not have to provide marriage license as we already proved we were married to get the probationary. And we had to provide an "affidavit of cohabitation" that we did not need earlier. Simple, but notarized, form saying that we live together.
Here are copies of what we just used. Each office is different... so I would take the Affidavit in for review before paying for a notary.
On the checklist numbers 6 & 7 are not required. Number 6 BI will do, and most of us do not come from countries that need number 7.
