We have an on-premises SharePoint 2013 and we want to migrate/upgrade it to SharePoint 2016. so which approach we need to follow? Migrating the farm or upgrading it and why?

Second question, if we have Farm solutions (including Event Receivers) & Sandbox solutions inside SharePoint 2013 will they work as-is inside SharePoint 2016?

Thanks

You would be better off upgrading to SharePoint 2019 or even SharePoint Server Subscription Edition.

Mainstream support for SharePoint 2016 ended in 2021 and the extended support ends in 2026.

    My advice is not to migrate/upgrade to a version of SharePoint that is out of mainstream support. Upgrading between versions of SP is usually better, since database migrations usually have a much higher percentage of success (usually 100%) where as file migrations can involve more errors.

From my experience is always better to migrate. For one particular reason, it will give you a clean slate.

No software product is perfect, and same goes for OS, having a fresh clean install of OS and SP Binaries goes a long way of clearing many small issues that are happening on OS patched over long time.

I tried only one in place upgrade and had a lot of issues, and switched to migration in the end.

  • but is doing migration the more standard way? so we do not have to worry about any issues and redeployment of the custom solutions?

  • You will always have to worry about custom solutions (and it doesn´t matter if you are doing in place or migration), You will need to either upgrade them or make them work in compatibility mode. Commented Dec 6, 2022 at 15:24
  • We are currently migrating large custom solution from SP2013 to SP2019 and it took us 1FTE 2 months to rebuild it. Commented Dec 6, 2022 at 15:27
