Upgrading smoothly from Uber Menu 2 to Mega Menu

Now i am in big problem .. while i implemented the above suggestions to rename
plugins directory to plugins-old — i had more errors ..
I renamed it back to plugins– and there were no errors — but today morning i found the entire website is not working

the error was of ubermenu()

Fatal error: Call to undefined function uberMenu_easyIntegrate() in /home/content/19/10289519/html/itcindia/wp-content/themes/itc/header.php on line 38

Now i did the most stupid thing – i went to plugins and found that this plugin Uber Menu 2 was deactiviated … I deleted it >>>>

wow .. then nothing happened ..
Then i releaised none of the plugins were activiated ..
I activated all of them and voila — the original error were back in the plugins section of dashboard ..
But the site was not working

Fatal error: Call to undefined function uberMenu_easyIntegrate() in /home/content/19/10289519/html/itcindia/wp-content/themes/itc/header.php on line 38

what is more BEAUTIFUL is that in the new plugins i cnanot find Uber Menu 2 …
It is no longer available

I also realised that my wordpress was version 4.2 something – so i went the in the application control panel and updated it from there

I don;t know where i am headed .. but I think i need help in Transforming from Uber menu 2 .. to Mega menu
