Migrating SharePoint Custom Farm Solution (WSP) from SharePoint 2016 to Subscription Edition
Hello Everyone, We all know that we can migrate SharePoint custom farm solutions (WSP) from SP 2013 to SP 2016 and then to SP 2019. I am trying to find out if there are any official guide documents from Microsoft that provide information on the compatibility and process to migrate SharePoint 2016 Farm solutions (WSP) to SharePoint Subscription Edition (On-Prem). If anyone is aware of any information from Microsoft regarding this, please advise. Additionally, when migrating custom farm solutions (WSP) from SP 2013 to SP 2016, SharePoint takes care of the .NET Assembly redirects. This means that the SharePoint 2013 DLLs will be automatically redirected to the SharePoint 2016 DLLs. In most cases, there is no need to rebuild the source code in .NET 4.6 (https://sharepoint.stackexchange.com/questions/288408/custom-solutions-upgrade-is-required-from-sp-2013-to-sp-2016. Does this redirection mechanism work the same way for Subscription Edition as well? Please advise.
