We are at version 3.8 so we need the following:
Upgrade to current version on our "sandbox" - we'll need to verify that home-made and commercial plugins work.
Upgrade LIVE site to current version.
All within 1-2 months
Please PM me with quotes
Core and theme upgrades are also simple. However, 3rd party plugins, you need to contact the developer if they have a new support version yet.
I sent you a PM regarding it. Please check and let us know.
