Current Leased License 3.8x
 

My current leased license is about to run out. I understand I'll need to buy a 4.0 license. However, I need to know if this still covers 3.8? I.e., I really don't want to upgrade now, or for quite some time. Is there an option to maintain my current 3.8 site with a different cost package or must I buy the 4.0 and upgrade immediately? Thank you.l
