NEWS! Migration timeline changed and test period extended. Changes to migration timeline and further testing. Announcement of ECPDS migration. |
Transition plan
As part of our Data Centre move we have started the installation of ECPDS, the ECMWF Production Data Store, in Bologna. ECPDS, which is described in a Newsletter article, takes care of both the dissemination and acquisition of data. For the migration of the dissemination we are currently considering two options:
- Incremental move of individual data streams
- Switch-over of all data streams together with the switch-over of the operational forecast
We will confirm at a later date which option will be used.
As a first step to prepare for an operational ECPDS in Bologna we are asking recipients of operational data to make changes to their network setup. We will also offer transfer tests to ensure that external hosts will be ready for the switch-over of the operational forecast production from Reading to Bologna, expected for June late September 2022. Please note that until then the operational forecast will continue to originate from our Reading Data Centre. A separate page regarding the release candidate test phase of the forecast production will be published soon.
Indicative timeline
The operational switch-over is currently expected for June, date TBC. late September. The migration of dissemination users to the ECPDS in Bologna is scheduled to happen in September, close to, or on the day of the operational forecast switch-over. Al dates TBC.
