My wife has an iPad 2 with iOS 6 backed up to her 2006 24"iMac running Snow Leopard. She's about to get a new iPad Pro 9.7" to replace it. She only uses her iPad for Calendar, email, Contacts and Facebook. So really the critical stuff is priority one Calendar and contacts. Will that old setup play nicely restoring a backup to the new iPad Pro? Would the old iMac, now 10 years old but going strong, even accept the new iPad given that iTunes is not the latest?
