English: Yes. Well, on a temporary basis there will have to be some re-keying from one system to another. I think that, to a degree, customers will be able to use the system; there's no doubt about that. But in order to ensure that the system does work, between now and go-live we are doing what is called beta testing. So, we're testing with people who will be customers and people who will be using the system, and this testing, actually, will be commencing next week and continuing until February. When we are content with the feedback that we receive from those testers, then we will allow the registration to be circulated more generally. That will happen in February - almost entirely in February. So, we now have until April. In terms of monitoring, what we're doing, for example - . There are - I think I have the figures here - 15 milestones between now and 1 April, and what we're doing is that we're noting each one of those on a page. We have a mitigation for each of them, and then we have a contingency plan that asks, if certain things happen, what happens next. And then that is all linked into ongoing contingency plans - what we would call business continuity for the WRA - because if there are things that could go wrong between now and 1 April, they could also go wrong in September. So, we have 15 milestones, so what we're doing is putting contingency plans in place for all of those and then we have 25 scenarios. So, there will be contingency plans for each of them too and that shows that there is a specific individual who will have to be responsible for those. We have something that demonstrates what would happen if, for example, there were to be an outage in one of our systems for half an hour, for 24 hours, for a week, for a month. So, everything that you could do in preparation has been done. It doesn't mean that nothing could go wrong, but at the moment we've covered all our bases.
Welsh: Dyna fo, ie. Wel, dros dro bydd rhaid i ni wneud re-keying, basically, o un system i'r llall. Felly, rwy'n meddwl, i raddau, y bydd y cwsmeriaid yn medru defnyddio'r system; nid oes amheuaeth am hynny. Ond i wneud yn siwr bod y system yn gweithio, rhwng rŵan a go-live rydym ni'n gwneud beth sy'n cael ei alw yn beta testing. Hynny ydy, testio efo pobl a fydd yn gwsmeriaid i'r system, pobl sy'n medru defnyddio'r system, ac rydym ni'n testio efo nhw yn cychwyn, actually, wythnos nesaf, ac mae hynny'n mynd ymlaen tan fis Chwefror. Pan fyddwn ni'n fodlon efo'r feedback rydym ni wedi ei gael oddi wrthyn nhw, mi fyddwn ni wedyn yn gadael i'r registration fynd allan i bawb. Bydd hynny'n digwydd ym mis Chwefror - bron i gyd. Felly, ar hyn o bryd, mae gennym ni o rŵan tan fis Ebrill. Er enghraifft, o ran y monitoring, beth rydym ni'n ei wneud ydy - . Mae yna - rydw i'n meddwl bod gen i'r ffigwr - 15 o milestones rhwng rŵan a 1 Ebrill, a beth rydym ni'n ei wneud ydy nodi pob un ar daflen. Mae gennym ni mitigation ar gyfer pob un ohonyn nhw, ac wedyn mae gennym ni contingency plan sy'n dod ar ôl - sef, 'Os bydd hynny'n digwydd, beth sy'n digwydd wedyn?' Ac mae hynny wedyn yn cael ei gysylltu efo ongoing contingency plans - hynny ydy, beth fuasem ni'n ei alw'n business continuinty i'r WRA - oherwydd pethau sydd o bosib yn mynd o chwith rhwng rŵan a 1 Ebrill, mae'n hen ddigon posib y bydd o'n mynd yn rong ym mis Medi hefyd. Felly, beth rydym ni'n ei wneud yw bod gennym ni 15 o milestones, contingency plans ar eu cyfer nhw i gyd, ac wedyn mae gennym ni 25 o scenarios, felly mae yna contingency plan iddyn nhw a phob un ohonyn nhw'n dangos i chi bod rhywun yn benodol yn gorfod edrych ar ei ôl o. Mae gennym ni rywbeth sy'n dangos beth fyddai'n digwydd pe bai yna, er enghraifft, outage yn un o'n systemau ni am hanner awr, am ddiwrnod, am wythnos, am fis. Felly, mae pob dim y buasech chi'n medru ei wneud ar gyfer hynny wedi cael ei wneud. Nid yw hynny'n golygu bod - . Mae'n bosib y bydd rhywbeth yn mynd wyneb i waered, ond, ar hyn o bryd, mae pob dim wedi cael ei wneud.
