I am upgrading Sitecore xConnect from version 9.0.1 to 9.1.1 and after following steps from the Sitecore-911-Upgrade-Guide, I copy & pasted the provided files and folders to the xConnect folder. But now I cannot start Sitecore Marketing Automation Engine service anymore.

I am getting this error in the logs:

"The certificate was not found. Store: My, Location: LocalMachine, FindType: FindByThumbprint, FindValue..."

I checked all connection strings to check thumbprint and they look fine. Any suggestion? It is weird that it doesn't work after copying files, especially since I didn't change any App_Config folders.

    Make sure the certificate permissions allows the service to access it. Jun 26, 2019 at 11:08
  • I use the same App_Config folder as for version before copy & pasting files and it worked then. Jun 27, 2019 at 8:29
  • Check the certificate with the thumbprint exists. If it does check that the issuer cert is in the root store and all are certs have not expired. Expiration date is based on license file. Have a look at my answer on this ticket sitecore.stackexchange.com/a/20155/2402 Jul 29, 2019 at 13:52
