Old system upgrade to 4.x


We run an old 1.8xx system and I think its well overdue for an update…

Reviewing the documentation I have no upgrade path to a later version so I will have to do a restore to 2.210.x.

Can I restore straight to 4.x using this (http://wiki.freepbx.org/display/FD/Upgrade+from+FreePBX-Distro-1.8xx.210.58+to+FreePBX-Distro-2.210.62) as a guide or do I need to go through the 2.10 > 3.x > 4.x script upgrade process?

Thanks in advance.


You can restore right onto 4.x
