We are planning implement SharePoint 2019 on-prem to replace existing SP 2010 intranet . we have few SP visual webparts with SQL data sources that was build using VB.net . we like to know if it is possible to migrate SP2010 .wsp solution to SP2019 (webpart -server side /Client side) or any clear guidelines/instructions how to develop visual webpart solutions (with SQL database) for SP 2019 on-premise .
I do apologize for my lack of understanding all this different framework . Thanks in advance
