State of knowledge

estos will determine the final interference type. 

This does not specify any prioritization in terms of processing time.

Description of interferences

P1-P3 reports that follow our instructions at https://support.estos.de/en/support/leitfaden-ticket-erstellen-fuer-estos-support will be preferably processed.

General note

Before any update or major change, the partner must always create a backup, whenever technically possible, to ensure that restoration is available.
This is intended to prevent more extensive restrictions after an update or major change from impacting the operations of the end‑user company.
