This. Upgrade but don't do it it too soon. Some companies don't upgrade their OS for years. Not due to licensing, but due to stability issues. Wait a while till the bugs are ironed out, then upgrade. For a company I would suggest wait at least 6-12 months before an upgrade. Obviously apply security patches regularly.
