Hi KDM
Only your daughter can decide whether she wants to apply for PIP. I can understand her reluctance as applying for any benefit is a stressful experience, and clearly, her medical conditions make it additionally challenging.
If she decides that she doesn't wish to apply, I don't think that puts her at a disadvantage when migration takes place. There are plenty of claimants who only claim ESA/UC and who never apply for PIP.
