I have MCS7825-I4 , which in on the compatiblity matrix for the 8.6.1-20000. After upgrading from 8.0 to 8.6.1-20000, none of the services are operational. It just gives the message "This hardware has limited functionality. Backup and Restore is the only supported functionality". I understand that this message is for bridge upgrade, which is not the case here.
Actually the problem was memory being 2GB on MCS7825 machine. Cisco document says that 'its recommended' to have 4GB RAM, whereas in reality, its mandatory to have 4GB. Also, its important to note that memory should be upgraded prior to upgrade and it does not work if you upgrade memory after software upgrade.
