Completely rewrote acronis-update.sh to actually perform upgrades: Features: - Checks current version before upgrade - Shows service status - Two upgrade methods: 1. Automatic (web console instructions) 2. Manual (downloads and runs upgrade) Manual Upgrade Process: - Detects existing installation automatically - Extracts cloud URL from /etc/Acronis/Global.config - Downloads latest installer from correct region - Runs installer in unattended mode (-a flag) - Installer automatically upgrades over existing installation - Preserves configuration and registration - Shows version before/after upgrade - Verifies services running after upgrade - Offers to restart services if needed - Cleans up download files What Gets Preserved During Upgrade: ✓ Agent registration (stays connected to account) ✓ Backup plan configurations ✓ Connection settings ✓ Service configurations Based on Acronis documentation research: - Running installer over existing installation = automatic upgrade - No uninstall needed - No re-registration needed
