Hello,
https://dev-private-review.linaro.org/ has been upgraded to Gerrit 2.10.6. Upgrade went smooth, the only issue is that handful open reviews there are now in "Merge Conflict" state, as discussed below. However, I tried to merge a test review with such status and it went OK. If that won't work, a change need to be rebased and re-pushed from command line.
To remind, the biggest change in 2.10.x is a new change summary screen. Every user will be notified about it via popup on first access, linking to detailed documentation: https://dev-private-review.linaro.org/Documentation/user-review-ui.html and offering choice to switch back to classic screen (support for which is dropped in 2.11, so use your judgement when you want to learn the new screen - now or later).
Please let me know of any issues seen. If nothing big pops up, we'll finish 2.10.6 migration next weekend, upgrading https://review.linaro.org and https://lhg-review.linaro.org as discussed below.
Thanks, Paul

Hello,
As was announced previously, Linaro Systems team is working to upgrade Gerrit version used on our hosts from 1-year old 2.8 to recent and supported 2.10. Two weeks ago, we upgraded https://android-review.linaro.org as a pilot. The upgrade went largely OK, though as full disclosure, following issues were faced:
- Upgrade uncovered issues with duplicate accounts. This issue is
mostly specific to android-review.linaro.org - it's the oldest Gerrit system in Linaro which accumulated number of accounts from different authentication services we used as well as community accounts. Other systems are unlikely to be affected at all, and even on android-review.linaro.org only few active users were affected and issues were resolved proactively.
- 2.10 exposed an AJAX caching issues we experienced intermittently
before - just to allow to nail them down and resolve consistently for all servers. So, this is off the list.
- The "biggest" issue we saw is that after the upgrade, all pending
open changes in Gerrit were changed to "Merge Conflict" state, which was not resolvable from UI, with Gerrit suggesting to rebase and re-push change from command line. Having done that, a reviewed worked without a problem. We even received a report that this issue may be related to the new review UI, switching to old screen allowed to rebase a change via UI button.
With this in mind, we think we're ready for the next round of upgrade. Based on previous discussions, this would be https://dev-private-review.linaro.org , slated to upgrade next weekend. We'd like to confirm that this plan works well for them.
Otherwise, we'd plan to finish Gerrit upgrade (and do any needed follow-up tweaks) before Connect, so there was productive work there (and we can consult people on new UI/features they may want to use). So, if everything goes smooth with dev-private-review.linaro.org, a weekend after next (Sep, 5) we'd plan to upgrade 2 remaining systems: https://review.linaro.org and https://lhg-review.linaro.org . Again, we'd like to be sure that their stakeholders are OK with this.
Thanks, Paul
