SI Content Release Lead to check Daily Build RVF report daily to ensure no failures in the "Traceability Service" assertion(s). These will provide advanced notice of the type of failures we currently don't find until Release time (items missing from the RF2 manifest, package formatting issues, etc), so that they can be fixed well before the release.
28 Sep 2023	12:00	SI Devops Team	Setup new automated JIRA tickets to be generated from the parent International Release ticket, for all Mapping steps below (both internal and external)
28 Sep 2023	12:00	SI Content Release Lead	No further batch loads or bulk updates. No further promotion for projects that have large scale changes for example promotion from the Community Content or changes to foundational hierarchies likely to have impact across other content.

(cannot move this meeting earlier as Content Release Lead needs enough time to run full validation after cut-off before this handover meeting)
06 Oct 2023		00:01 - 05:00	WCI	00:00 - WCI to SUSPEND DRIP FEED FOR TONIGHT AND TOMORROW NIGHT *02:*	*20 - SI Devops to schedule automated rundeck job for 02:20 on the Friday before Versioning - this will completely remove SNOMED from the Mapping Server + upload the latest version.* 03:00 - WCI to validate the Release Mapping Server 04:00 - WCI to lift maintenance window and allow Mapping Team to access other projects ONLY (GMDN, MedDRA, etc)
06 Oct	2023	09:00	SI Mapping Team	Mapping team to finalise any mapping from the final content promotion after the 12:00 content cut off previous day (or any issues identified during the Mapping Server validation process), and then Resolve their "Mapping Complete" ticket to confirm that "Mapping QA complete". NB: this is using the content from yesterday's final promotion cut off at 12:00, as the Daily Build feed then ran at 01:00
06 Oct	2023	09:00	SI Content Release Lead	Final content review and validation in the current release branch: Confirm root concept has been updated. Review RVF report. Review MRCM report.

06 Oct 2023	12	14 Oct 2022	:00	SI Content Release	Lead	SI Content Release Lead to run map process: Frequent Release - Updating ICD-10 and ICD-O Maps for Close of Release confirm with SI Map lead that the Mapping cut off was completed successfully at 12:00 create 2x new tasks in authoring platform project 'Release mapping upload project', to accept the upload of the new Map files Delta's (one for SimpleMap + one for ExtendedMap delta files). upload the new map Delta files into the branches, validate + promote the two Map file tasks to MAIN Backup plan: If there is a Critical (P1) issue found in the final content (shouldn't be due to the new task/project validation, but we need an emergency process just in case), then WCI can import a specific fix branch straight into the Cloned Release Mapping Server, without bleed through from the next month's content. However, this should only be used in the genuine emergency situations... confirm to SI Release Manager once complete, and full Release validation can begin
09 Oct	2023	12:	00	SI Release Manager	For the first few releases the SI Release Manager should run an initial full Release against the UN-VERSIONED content, to ensure no failures in the "Traceability Service" assertion(s) in the RVF report. These will provide advanced notice of the type of failures we currently don't find until Release time (items missing from the RF2 manifest, package formatting issues, etc), so that they can be fixed well before the release. Versioning to proceed once SI Release Manager confirms that there are no Critical issues in this build. ***** NOTE there will be some false positives in the new Traceability Assertions (assertionUuid: "b7f727d7-9226-4eef-9a7e-47a8580f6e7a") until the map files can be finalised and uploaded to the termserver (see below) the number of failures should exactly match the number of records across BOTH map file delta's - so if this is the case these can be ignored until the map files are uploaded to the termserver in a few days...
09 Oct	2023	16	.00	SI Devops Team	If any Critical fixes have been required, we need to: Push them back through to MAIN before versioning Re-run the Daily Build manually in order to ensure that the Mapping Server picks up the latest version
10 Oct	2023	15:00	SI Release Team	Final handover meeting - final cross check to ensure that all Release validation complete, and any last minute tasks (refset generation, final Mapping updates from last night's drip feed, etc) are complete before versioning green lit.
11 Oct	2023	12:00 - 17:00	SI Devops Team	Technical team release tasks (as and when initial validation is signed off at each milestone) * Maintenance screen to be raised in Production * *termServer branching and Release versioning (DevOps to raise tickets themselves as per Terance's request)* VERSIONED BRANCH SENT TO SI Release Manager FOR FINAL VERIFICATION (see below) BEFORE CONTINUING FINAL TASKS... Snapshot used to provisionally bring the AP validation etc back up again today, so that it works for the interim period until the new Production release package is signed off tomorrow (on the 16 Nov this cycle)... Provisional date to drop Maintenance & re-open Content authoring for next editing cycle - providing no Critical issues identified... * Maintenance screen to be lifted in Production * Once authors confirm Editing has re-commenced: run the test upload into Dev browser to ensure no issues. re-configure the Daily Build + Daily Build browser to work in the next Editing cycle - Browser Daily Build Process Performing this step early allows the daily build to report on the next monthly release content, for both authoring validation and external use. New unreleased content will hidden in the main browser until the effectivetime. If any content has to be removed due to urgent issues we will need to back-out and reimport the International data. Reminder to WCI to cut off mapping drip feed (but NOT clone over to Release Server until Mapping Team confirms that both ICD-0/ICD-10 + GMDN maps are all updated based on Content + latest GMDN content.
11 Oct	2023	09.30	SI Release Manager	New versioned Release Build (including both ICD-0 + ICD-10 maps from termServer) is created and validated by SI Release Manager ***************************************************************************************************************************************** THIS BUILD MUST BE DONE WITH x PREFIXES REMOVED + USING PRODUCTION NAMING CONVENTIONS SO DEVOPS CAN USE IT *************************************************************************************************************************************** * MANIFEST CHANGED TO PULL MAP FILE DATA FROM SNOWSTORM INSTEAD OF EXTERNALLYMAINTAINED FOLDERS ****

Approximately 18.00 UTC - AUTHORING + MAPPING RE-COMMENCE

Restart content editing for the next release cycle in the new release branch on authoring platform.

Project promotion is also clear to commence from this point onwards.

Content Release Lead -

Maria Braithwaite SEND NOTICE to Content team members - all existing tasks must be rebased to prevent problems with the classification (until we can automate all rebases then rebasing the tasks is also needed. Dev Ops will still rebase all projects each release).

Mapping Drip Feed switched back on (but mapping tool will not be back up to date until first drip feed run later tonight).

Once Final, versioned Release Build is signed off by SI Release Manager, it is handed over to DevOps to update the Daily Build, plus all AP validations, etc

As this can take a few hours or even more, in the interim DevOps will use the provisional Snapshot release from the versioning process in order to ensure minimal downtime for these services.

Once Release Manager confirms Production release is published:

Update all Production systems (authoring platform, browser) using the final S3 published package.
This needs to include the new Release Stats page in the browser (https://browser.ihtsdotools.org/qa/#/descriptive-statistics), which can be updated using step 7 ("If this is the final INT release we need to also update the Stats") in these instructions: https://confluence.ihtsdotools.org/display/DEVOPS/Browser+Release+Updates
- NOTE: For the initial soft launch Releases this will just be tested in Dev/Uat browser rather than Prod to avoid confusing users
From September 2020 ensure that the GPS ValueSet is available through the FHIR API ie https://browser.ihtsdotools.org/fhir/ValueSet/gps
