one time oppertunity

Am I right in thinking that if someone was under the age of 65 and on DLA middle rate care and lower rate mobility and are now being transferred over to PIP and are over the age of 65 then they have a one time opportunity to access the enhanced rates of both the components

Gordon, perhaps I didn't explain enough my query is that under that criteria then they are able to access the enhanced pip rates for the first time even though they are over 65

So previously for example anyone who received say lower rate DLA or standard rate PIP mobility and request a change of circumstances after they reach 65 or if it is their second or more PIP assessment they cannot go from a lower/standard mobility award to an enhanced mobility PIP award, but when they are told by the DWP that their DLA is ending and they need to apply for PIP and have reached the age of 65 or over and their mobility needs are greater then and only then they could go from lower rate DLA mobility to enhanced mobility rate PIP
