1 Transitions

Rémy

• Rémy presented the slides on the transition form GTS/WIS to WIS2.0: What, how, who and when: a proposal (to be updated) :

• Replacing the real time data exchange (the GTS) by the new method (WIS2 messages and download) between members

• Replacing/updating WIS1 technical solutions

• Upgrading/replacing Message Switching Systems  in their exchange with local systems

• Overarching principles of GTS to WIS2 transition

• role of GISCs in transition to WIS2

• The transition from WIS1 to WIS2

2 Discussions

ALL

• 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

• 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
