Hello,
Please refer the following steps for understanding
- The environment is SharePoint onlne (o365) with back-end being migrated from 2010 to 2013.
- Site Compatibility mode is 2010
- Sites are working in SP 2010 mode. 2010 features are available in the site.
- Once the compatibility mode switched off, what would be the impact on all the sites working.
- Which all features will stop working for sites.
Regards.
