Firstly thanks to everyone in advance for their time and expert insights. We have several servers (all at least 2012R2) that were overprovisioned due to vendor recommendations and I need to recapture some of the free space on these drives (mostly c: and d: partitions). I worked with VMware using their VMware converter 6.2 (our ESXi is 6.5u2) and we converted a low priority test system and it went okay. I am having some issues with the application on it, but as it is a standby failover server to the main application server I cannot be sure if the issue is VMware related re. conversion or if it existed before and I will talk with the vendor as the server and application seem okay otherwise. However, I wanted to get some insights from others that have done this, since my next candidate is a SharePoint 2013 farm (2012R2 o/s) that consists of a SharePoint 2013 Farm serer and a SharePoint database server running SQL 2012. Assuming there are no issues during the conversion process itself does anyone have any insights into if this is an okay thing to do or are there any issues that VMware is not telling me, because they said it was okay. Appreciate feedback.
