We are using SP2013 on-premise enterprise edition. We have a development farm and a test farm. Dev farm have one machine as WFE+APP and Test farm have 2 WFE and 2 APP. Both farm have separated SQL server (hence both are not using standalone installation)
We patched both farm with Lumension. Only Windows updates were patched to all servers in 2 farms. No SharePoint CU was applied. After patch, we run the Product Configuration Wizard in both farm and then reboot all servers. Everything have gone through successfully.
However, when we check CA > System Settings > Servers in Farm. The Configuration database version is 15.0.4719.1000 in Dev farm while the version is 15.0.4763.1000 in Test farm.
We also checked Upgrade and Migration > Check product and patch installation status. No missed patch found. In fact we can find the patch with version number 15.0.4763.1000 in Dev farm's Check product and patch installation status page.
We have checked Installed Update in window's control panel as well. Both farm seems have same update installed.
My question is, why the The Configuration database version is STILL 15.0.4719.1000 in Dev farm while the patches 4763 are in place?
