The decision
Choose the exact version, map storage and database format, and prepare an independent pre-change copy.
A bounded example
Test an isolated copy with representative data. Define a stop condition and return path before changing production.
Documentation
Use the relevant version of PostgreSQL — pg_dump before changing a live service.
Checks before change
Keep a recovery route, work on an isolated copy when data is affected, and record observations rather than assumptions. Stop if an acceptance check fails.
Limits
Hoszen does not preinstall or operate applications, hold secrets, verify backups, promise capacity or confirm a payment or VPS delivery.
