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
Action>> Rémy will update the slides taking into account that
Enrico> transition in 2024-2030, how feasible for this period? need KPIs for transitions. One KPI is about the completeness of transition.
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
