My company had 3 instances at one point after acquisitions. Two of them got merged so we’re stuck with two because of the number of customizations and the different sales approaches / teams between the two divisions. One of them upgraded to lightning required by some feature. The experience nice with lightning (even slower) has been worse than classic. Meanwhile the other instance is till on classic. We made the mistake of embedding business logic into sales force and integrated with their API only later to find out it can take upwards of a minute to just convert a lead to a contact via API depending on the current load on the system. Enterprise systems are fun.
