Timo> does principle 2 imply that someone operates a gts2wis "gateway"? how otherwise the center that migrated can interact with non-migrated centers without an MSS?
Rémy> yes there is a need of gateway GTS2WIS2 and WIS2 to GTS
Jeremy> principale 1 means that data are available for wis users and GTS users
Rémy> It’s more expressed in principle 3 no GTS data loss during the migration
Kai> First we need to have GTS data on WIS2
Kai> We need to distinguish center types for principle 3. If RTHs terminate their MSS, their downstream GTS centers will become detached from the GTS.
Rémy> Transition can start when GTS data can be received using WIS2 solutions(Enrico)
Action>> Rémy will update the slides taking into account that
Enrico> transition in 2024-2030, how feasible for this period? need KPIs of for transitions can be mentioned. One KPI is about the completeness of transition.
(David) Data with TTAAii shall not be exchanged over GTS.Podeur> the principle 4 is a key for transition to WIS2. New GBON data will only published on WIS2
Rémy>Countries that benefit from SOFF shall switch to WIS2
Peter> don’t see any thing about availability
Kai> Agree, we need to consider availability. If we start migration and the system is broken, it will be issue for transition
Peter> also WIS2 will exchange more larger volume data than GTS
We have two things: GTS transition and system related to GTS used at national level. Let’s start by GTS
Peter> in Canada we have MSS and we are using also file exchange mechanism, why not using the same for WIS2?
Rémy> If we consider the use of MSS in different cases we will never finish with the transition
Jeremy> you can provide this service by a local cache for this data
Peter> this is what we do, I think it’s not a problem if it’s files or APIs
Kai> I want to ask if it is a transition problem.
Peter> GTS to WIS2 is easy, what about WIS2 to GTS?
Rémy> As we are not talking about the transition and I have something else to do I will stop here
