If you are still using obsolete version of SharePoint for your Intranet portal or other business-critical application, you would be wise to commence planning your migration to SharePoint on Microsoft 365. Past the end of life deadline, you risk facing managing these challenges on your own: 

• Costly or no technical support.
  Without Microsoft’s regular patches and updates, you will be on your own with supporting an obsolete version of SharePoint. This will impact your user’s overall experience if your SharePoint environment (or your applications hosted on it) experiences any kind of ‘bugs’ or failures, resulting in extended downtime to fix an unsupported fix. That is if it is even possible. You may find a third-party vendor that supports an obsolete SharePoint version but not without incurring steep support costs.

• Increased security risks.
  Microsoft's regular patches to guard against modern-day hackers and cyber criminals will no longer be available post-end of life support of your SharePoint version. This leaves your organisation vulnerable to security breaches, not to mention the possibility of falling out of organisational compliance with industry regulations or standards.

• Future application incompatibility.
  Your organisation will continue to evolve and require new application functionalities to be added to your SharePoint environment well into the future. But meeting this goal by adding new features to a vendor-retired SharePoint version will be challenging, given its compatibility issues with the latest and modern applications.
