Hallo Community,
ich habe versucht meinen Mailcow-Server auf einen neuen Server zu Migrieren und bin dabei dem Tip von hier gefolgt:
https://mailcow.github.io/mailcow-dockerized-docs/i_u_m_migration/
und habe das backup and restore script dafür genutzt. Auf dem neuen Server habe ich ganz normal die Installation durchgeführt und dann das Restore Script gestartet. Es schien auch erfolgreich durchgelaufen zu sein. Doch wenn ich jetzt auf die Weboberfläche möchte, wird mir gesagt:

🐄 - we are on our way.
502

Ein Blick in die Logs verweist darauf das auf den SQL Server gewartet wird und der SQL Container gibt folgendes aus:

Also scheint doch irgendwas mit dem SQL Container nicht zu stimmen oder bei der Wiederherstellung ist etwas schief gelaufen oder habe ich etwas falsch gemacht? Auf jeden Fall bin ich überfragt was ich noch tun könnte. Eine erneute Wiederherstellung habe ich schon probiert. Leider ohne Erfolg.

Vielen Dank.
