Hybris Upgrade from 6.7 to 1905 issues?

[mohammed24]

Hi Experts, I am trying to upgrade hybris from 6.7 to 1905.So while doing upgrade i am getting build error's. For eg one of them is as below :

/cockpits/cmscockpit/components/contentbrowser/DefaultCmsPageContentBrowser.java (at line 16)import de.hybris.platform.cmscockpit.components.contentbrowser.CmsPageContentBrowser;
   The import de.hybris.platform.cmscockpit cannot be resolved

This is happening becuase cmscockpit extension is now deprecated in 1905 version. In the below API link i can see this(CmsPageContentBrowser) class is now removed.

My question is how to proceed further to resolve these type of issues? Do we have to add any jars?
