So I assume that I will be moved to the 14xxx from 10586 but remain on preview ring.
Right now... Fast and Slow Rings are testing Redstone 1 builds of 14xxx. This is the upcoming Anniversary Update. Redstone 1 is a
branch, the experimental branch. Just as Threshold 2 is the current
branch.
When Redstone 1 gets finalized (RTM) it will move to Release Ring and roll out OTA to Official/Production Ring (probably in waves).
Unsupported devices will not see any Redstone builds. Only the phones on this list will move to Redstone 1:
Phones Eligible for Windows 10 Mobile Official. Once Redstone 1 hits Slow Ring, I would expect all unsupported devices will get locked out of Insider and the door will be closed to them getting W10M (my conjecture based on what we have been seeing)...
If your phone is on the list of supported devices and you are on Official
or on Insider and have elected Production Ring
or are on Insider Release Ring you will be moved to the 14xxx builds from your current 10586 build when Anniversary Update goes live.
After some time (a couple of weeks) to congratulate themselves, accept praise, and unwind...
The whole process will start again and the W10M team will start pushing Redstone 2 builds to Insider Fast Ring and then eventually those will drop down into Slow Ring.
Official/Production Ring and Release Ring will continue on with 14xxx Redstone 1 builds until such time as the new Redstone 2 experimental branch is ready to go current.
Official and Production are the same thing with the provision that anyone on Insider who drops from a higher Ring down to Production stays where they are until Official catches up to or passes their build number. At that point they get OTA updates again and are back inline with Official. The only way to instantly revert from Fast/Slow/Release to Official is by using
WDRT and then getting OTA updates. If WDRT reverts you to 8.1 you must then use the
Windows Upgrade Advisor App to get back into the current branch.
To sum up:
- Fast Ring and Slow Ring of Insider test the experimental branch
- Release Ring of Insider tests the planned advances, patches and fixes for the current branch
- Production Ring of Insider is just a way of stopping future testing builds
Get used to seeing this cycle repeat. It's the new deal.
