How does cairim manage expiry date?

Introduction:

I just wanted to check how the CAIRIM program handles changes to license key.

If we ran CAIRIM with keys with a later expiry date it updates these expiry dates (viewing from CAILMP in SYSVIEW).

If we then rerun against the old keys with a closer expiry date it says it accepts the key for the cpu but when viewing
in SYSVIEW, the date is not altered and stays as the date most in the future?

So from what I am seeing if the current date is further in the future then running CAIRIM with a date close to today
current date is accepted by CAIRIM but doesn't alter the expiry date.

Is this how it should be ?

Answer:

It is the way CAIRIM program handles changes to license keys.

LMP will keep the key with the later expiration date.
