Trying to update my working 10.5.1 production Portal server and installs and brings up the Continue upgrade. Click and all seems to work and then get a popup error about SSL certificate. On checking the portal logs there a severe error "Migration failed. Web server SSL Certificate does not match list of certificates. Web server SSL Certificate does not match list of certificates."
Can uninstall 10.6 and reinstall 10.5.1 and all works perfectly again.
System is running on windows 2008r2 (fully updated with MS patches)
