@EdPa, thanks for the instructions.
SwOS upgrade via RouterOS console worked as described - after loading the RouterOS, try to upgrade SwOS using the
It seemed it did not even make any download or maybe even the installation - it was instant 1-2sec response "v 2.11"
It booted on first try and then rebooted SwOS without issues.
So we'll continue with SwOS as planned.

We noticed there were quite a few posts about dropped packets and errors on switches using RJ45 -> SFP+ ports.
We also had some warnings about dropped packets - Rx MAC Errors, Rx FCS Errors and Tx Pauses.
Mikrotik CRS328-24P-4S+RM (connected to US‑16‑XG via SFP+ cable & "FiberStore SFP-10GSR-85 A G1804125499")
Errors were reported by a server (netdata warnings) and onother computer connected to Gb ports on CRS328. But errors were registred (displayed on SwOS) only on SFP+ port 2, which is connected to Unifi 16-XG. Today we changed this connection to SFP+ port 1, using same module and cable and errors were mostly gone.
Was it due to SwOS update or switch simply prefers SFP+ port 1 - I do not know.
We then connected another computer with SFP+ cable directly to CRS328 > SFP+ PORT 2 and then tried multiple iperf tests:
Client (SFP+) > US‑16‑XG > CRS328 > Server (Gb RJ45)
Client (Gb RJ45) > CRS328 > Server (Gb RJ45)
Client (SFP+) > CRS328 > Server (Gb RJ45)
Client (SFP+) > CRS328 > US‑16‑XG > Server (SFP+)
GBit transfer speeds are full, 10Gb connections vary from 3-6Gb/s (but that could be due Proxmox, Windows in a VM, other running processes etc.)
Multiple tests did not produce any errors. After 1-2h Errors page looks clean whereas before it started showing Errors as soon as there was any real-life traffic going to the switch.
Maybe it will be helpfull to admins or some of the Mikrotik users.
p.s. thank you for the quick response. We saw some users/posts waiting for months being left with no solutions and some doubts regarding our decission going with Mikrotik already started to emerge.
We did our first regular SwOS update and "the music stopped". On a brand new, semi-flagship switch that is supposed to be the backbone of our small-biz GBit network.
This feels much better.
