TL:WR: so far I have mixed results:

- Profiles that existed before connecting to the new syncservice-rs, still sync with each other after switching to the new service.
- Profiles that are created after switching and only have experience with the new syncservice-rs, only sync with each other
- It seems these two groups don’t mix : no synchronization from one group to the other
- I _can_ send tabs from one group to the other though

Longer version:

I set out to test the new syncstorage-rs before decomissioning the old (still very much functional, albeit also very much Python-end-of-life) syncservice.

Test outline:

- I started with my regular profiles on a laptop, desktop and a phone being in-sync. I added a new profile to the desktop version, and let that sync as well. (Sync was maybe not instantaneous, but done within a minute, including copying and installing of existing plugins)
- Switched DNS from syncservice to syncservice-rs (with a path from [https://sync.domain.tld/ffsync/token/1.0/sync/1.5](https://sync.domain.tld/ffsync/token/1.0/sync/1.5), to [https://sync.domain.tld/token/1.0/sync/1.5](https://sync.domain.tld/token/1.0/sync/1.5) )
- Installed a new Firefox-based browser (nightly vs regular beta; “[FFUpdater](https://f-droid.org/en/packages/de.marmaro.krt.ffupdater/)” makes it easy to find various Firefox-variants) on the mobile (as Firefox on mobile lacks profiles), set up the syncserver URI to point to [https://sync.domain.tld/token/1.0/sync/1.5](https://sync.domain.tld/token/1.0/sync/1.5) and logged in to my Firefox-account
- open logs on my Yunohost to see if anything is happening  
`tail -f /var/log/syncserver-rs/syncserver-rs.log` and  
`tail -f /var/log/nginx/sync.domain.tld-access.log`
- Confirm that, yes, when I press ‘sync’ on either desktop or mobile, a call is done to the sync service
- Wait and find that, no, the phone does not receive any profile data

I let the mobile browser run for a while (an hour? Could be more, could be a bit less). No results.  
Next:

- I uninstalled Firefox Nightly, redid the installation and configuration. No improvement for the most part. It _does_ sync with the instance of Nightly that I had just uninstalled, so sync at some level does work (and storage does as well)
- I installed Firefox Klar. It does not seem to have Firefox/Mozilla account integration or sync capability out of the box.
- I installed Fennec F-Droid. Nice: this browser has quite a few settings by default that I have to change on regular Firefox. Synchronization though, no go. It does sync with the two Nightly ‘profiles’, but not with the others.
- As a test, on Fennec, I disabled all syncing, except for logins. After that I tried on Nightly to open a tab from Fennec: not possible: because the ‘send tabs’ sync feature was disabled _also_ in Nightly: the settings had been synced (this was via the third tab on ‘open tabs’ popup, left of ‘incognito’ tabs; long-click on an open tab and share → send to device still works, and can _also_ send to the clients that came from the ‘legacy’ sysnservice.)
- Finally, I thought of creating another profile on the desktop, that would sync with the new syncserver-rs, so would never have seen the old syncserver. That profile is somewhere in the middle, worst-of-both-worlds:
  - It has a single extension from my synced profiles (desktop-side) but lacks all the rest
  - It is not visible (and does not sync) with my mobile ‘new only’ synchronizations
  - “Send tab to device” does work, for sending and for receiving
  - As opposed to the other desktop-profiles, this profile does not have an “about:sync” page, only the “about:sync-log” page
  - What? While checking the error logs (about:sync-log, or ~/.mozilla/firefox/profileano.t.ao.3/weave/logs ) I just found I made a copy/paste mistake, and tried syncing to the non-existent (at the moment) _old_ syncservice! No wonder nothing got synchronized; very peculiar the tabs could be sent to another device none the less!
  - upon correcting the URI, I still get a 404 on the _correct_ link for the service

It seems that ‘new’ synchronization targets can sync with none of the accounts that have _ever_ touched an old sync service.

To be continued, for sure!
