Hello,
I've been trying two time to update one instance of our projeqtor ( they are copies of each other from start so only custom fields changed in between them)
Once from 9.5.5 to 10.2.2, and after failure, from 9.5.5 to 10.0.6
Our main instance is on 10.2.2, and our testing instance is also on 10.2.2
We don't understand the problem as the configuration files in server are the same as the testing and main instances
But the one used by more a sensitive service stayed in 9.5.5 because we wanted to be sure to have a window where they don't use it to update it
Here is the log for the update I tried this night
Launched at 3 AM and checked to see at 8.55 AM
Could you help us ?
Thank you
It is the convertion to UTF8_MB4 that fails.
Error is : MySQL server has gone away
Check is MySql error log why server closed connection (timeout, out of memory, ...).
