After migration I cannot backup and restore database.

[Warning] Aborted connection  to db: ‚otobo‘ user: ‚root‘ host: ‚localhost‘ (Got an error writing communication packets)

I have already increase some mysql parameters like wait_timeout, net_read_timeout, net_write_timeout. I also have checked database.

 

Any suggestion?

Thank You for help.

Fortunately I have managed to solve to migrate database. Before load back database I have modified some mysql parameters.

I have logged in my mysql database as root and set the next max values.

> docker exec -it  otobo-web-1 bash
> mysql -h db -u root -p

SET SESSION wait_timeout=31536000;
SET SESSION wait_timeout=31536000;
SET GLOBAL interactive_timeout=31536000;
SET GLOBAL max_allowed_packet=1073741824;

My  migration steps:

1.)  Install otobo docker version.  Create the same config as I have used in  otrs. Install packages what I have used in otrs.

2.) Use  script to migrate db on otobo-web-1 container. ( 5.14.2 Optional Step: Streamlined migration of the database (only for experts and
spezial scenarios) )

scripts/backup.pl -t migratefromotrs --max-allowed-packet 1G --db-name otrs --db-host=x.x.x.x --db-user dbadmin --db-password PASSWORD

3.) Reload database on otobo-web-1 from the directory where migration createed sql files.

mysql -h db --debug-check --debug-info --max-allowed-packet=1073741824 -u otobo -p otobo < otrs_pre.sql

At the bottom I managed to migrate database.
