I'm working on upgrading one of Magento site version 1.7.0.2 to 1.9.1.1 via Magento Connect. For some reason after I click on "check for upgrade" button, the page does not show any drop options except "reinstall" and "uninstall" on the available column, all fields are empty where they were supposed to version 1.9.1.1 or the latest version of modules.
This issue doesn't occur on another Magento site that I upgrade from 1.9.0.1 to 1.9.1.1.
Could this be permission issue or glitch on Magento connect? or does upgrading from 1.7.0.2 to 1.9.1.1 has be done manually outside Magento Connect at this point?
Thank you,
