...did mine last year and relinquished my C1* (which needs a medical which will cost you - not that I would have expected to fail). If you want to keep C1 it can't be done online.
Online, with my photo taken from my passport records - ever so simple and quick.
(* given I drive a motorhome, there is a remote possibility I might want to reinstate my C1 in the future - I have owned motorhomes over 3500kg MTPLM in the past - it isn't a particularly onerous process to do so (with the requisite medical) but it pays to keep a record of the original entitlement).
There have been some complaints in the past about the licence being dated from the date of application/issue (which could be a pain, since it's three-yearly renewal from here on in), but mine was dated from my 70th birthday.
