As you might already know (or not), End of Service for DevTest versions 8.1, 8.2, 8.3 and 8.4 are coming up soon on July 1, 2017. This means that the above mentioned versions will not be supported after July 1. If you are one of those that are still on those releases (or even prior ones), this would be a good time to start planning for the upgrade to the latest release of 10.1.
I would be more than happy to discuss this with you. Please reach out to me at email@example.com for any questions/concerns or to simply discuss the upgrades.
