Improve this question

Please, can someone help. I need to migrate custom visual studio .wsp solutions from SharePoint 2013 to SharePoint online, how do I go about it.

Answer 1

Unfortunately these will have to be rewritten as they are not supported in SharePoint Online.

Depending on the solution you can rewrite these as SharePoint Add-Ins or as client side solutions using SharePoint Framework.

Answer 2

There are are two types of solutions (wsp) in SharePoint on-premise:

• Sandbox and
• Farm solution

We used to deploy the sandbox solution to SharePoint online till the year 2016 now does not support, but we cannot deploy the farm solution

So, if you have a farm solution, you need re-develop the functionality or solution using the modern SharePoint technology - like SPFx framework.
