Moving 3CX to Server 2019

[xspance]

Hey Guys,

I need some help. I am migrating an instance of the 3CX to server 2019 to move to V16. I have already done this on one site and the backup and restore procedure just worked.

With this instance when I run the restore it seems to get stuck with about 5% left. I left the restore running for 1 1/2 hours. I cancelled the restore and rebuilt the server as its just a VM. I took another backup from the working server running on server 2012 V15 SP6 to make sure the backup wasn't corrupt. The system is quite large however is only used for internal calls from gatephones and there are no external SIP trunks, roughly around 2000+ extensions and voicemail is not used. I am not getting any errors the restore just seems to be hanging.

What can i do to check to make sure the original backup is not corrupt and what tools can i use to monitor the restore to see if there is anything failing and the restore is just hanging?

I have this link: https://www.3cx.com/blog/docs/backup-restore-troubleshooting/ is this something i should be following? Will it give me the details i need to get this migration working?

Thanks in advanced.

Matt

Hi Matt,

You reference the link about about backup and restore for existing systems (this does not mean migration - this means restoring a backup on an already running instance)

The restoration is performed during the installation of V16 (by selecting the option to restore from backup taken previously).

Can you elaborate a bit more?
