Option to keep ZxChat in Zextras 3.0 update?

I like to keep my Zextras version as up to date as possible but the 3.0 change from zxchat to team was a surprise I wasn't expecting. I can't just spring a change like that on our staff without a lot of forewarning, discussion and training. Our staff use the ZxChat feature extensively.

Is there an option to upgrade Zextras to 3.0 and keep the old ZxChat for a while?

Thanks
Rois
