Before and after surgeries I used the same Facebook profile, changed my handle and did the following which I consider tips for those who are transitioning

• When Facebook suggest reposting old post, review comments first for any references to your old identity e.g. someone said "Hey Kevin" while now I'm Karen, get the hint.
• Move old identity photos to a hidden folder or delete them. I elected to place the photos into a hidden folder.

Now I do realize many will elect to have one current profile and one for their secret identity, me, I recommend one profile, get it out there and be proud.
