Will changes made in our test configuration be carried over into production?
Yes, due to the nature of the upgrade, ECMWF will transfer all installed requirements in the test PREd to the production system on the day of the cycle implementation. During the RCP, any changes made in the production system should also be installed in the test system to ensure continuity.

Will test 50r1 data be pushed to me automatically?
If you're a Basic/Bronze user, the Data Support team can push a test batch of IFS Cycle 50r1 data to the host configuration.
If you're a Silver/Gold user, then you can either push the data to yourself or set the data to be delivered in 'NORMAL' mode. If you put the data in 'NORMAL' mode, the data will be disseminated to your host automatically. However, the data are disseminated between operational windows to protect network capacity, meaning the data will not be disseminated according to the usual dissemination schedule. There is no fixed delivery schedule, and products may not be available in real time, delays of up to one day are possible.
Note: 'NORMAL' mode will not be available until w/c 2nd March 2026.

What delay can we expect from Can I use the test data compared to the operational dissemination of the data?operationally?
No, the test data are strictly for non-operational use. Test products are intended for internal testing and validation only and must not be used in operational services or shared on social mediaThis varies from day-to-day and depends on the data set as well. Some days the delay is a couple of hours, while some days there might be a day or two lag. Usually as we get close to implementation the delay gets smaller.
