End of Life Products and Features - Manually Removing M3

Removing M3 from a PBX happens automatically. However, you can do it manually

To remove all tasks and processes:

yum remove sensu*
service openvpn stop

You should also remove the M3 Yum repository, to avoid accidentally installing any M3 packages again

rm -f /etc/yum.repos.d/m3.repo

There will still be some files left over, which you can happily disregard, or remove, that are as follows:

/etc/m3-defaults.conf
/etc/m3.conf
/usr/local/m3/*

Simply removing the M3 package is sufficient

yum remove m3

You may also drop the m3 database (which will be called 'm3_development', or 'm3_production' when M3 is out of beta)

mysqladmin drop m3_development
