Reevaluate the access point and references in the context of RDA before recoding the record as RDA. That could very well mean that you change the form of the access point. For example if a new form is the predominant form or the form by which the person is now commonly known, it should be changed.
For your second question: check the LC-PCC PSs! The answer can usually be found in RDA or them:
LC-PCC PS for 22.214.171.124
New Authority Records:
LC practice/PCC practice for Optional addition: Apply the option to provide a fuller form of name if a part of the forename or surname used in the preferred name is represented by an initial or an abbreviation, if the cataloger considers it important for identification. Add unused forenames or surnames only if needed to distinguish one access point from another (see 126.96.36.199).
Existing Authority Records:
LC practice/PCC practice for Optional addition: Unless otherwise changing an existing heading (e.g., conflict), do not change an existing AACR2 or RDA heading merely to add or remove a fuller form of name.
