I tried to upgrade my d365 and retail environment to latest released hotfix from update 3. I have completed all the process as stated on the following blog
https://ax.help.dynamics.com/en/wiki/installing-deployable-package-in-ax7/
Also, install the package referring https://ax.help.dynamics.com/en/wiki/configuring-and-installing-a-metadata-hotfix-package/
After upgrade process, the retail server is upgraded and shows in the versions too. See below all versions before and after an upgrade.
But surprisingly I cannot see the libraries upgraded in the bin folder of the retail server (C:\RetailServer\webroot\bin).
Do I have to perform some more steps? If libraries not upgraded then how the version is updated? Any help will be appreciated.
