I’ve inherited an Asterisk 11.3.0 box running FreePBX 2.11. It was manually built by the prior vendor instead of using the complete Official FreePBX distro, so I get this same error.
Is there some way to manually “upgrade” this install so that System Admin Updates, etc., work as they should?
You are in luck, a new tool has been developed for situations like yours to assist in migrating your system settings to a fully supported platform:

I did see that, but this customer is not going to “go” for purchasing another server for the migration. Is there any way to do this in-place?
