Update remote components
For the most part, only very general advice can be provided for updating the remote components because of the wide differences in platforms and tenancy systems. The following two sections provide some guidance.
Update remote components in a provider-hosted add-in
For a provider-hosted SharePoint Add-in, you update the remote components using the best update practices of the platform on which the components are hosted. Just as the remote components of a provider-hosted add-in are installed separately from the installation of the SharePoint Add-in itself, they are also updated separately. Some points to consider:
The updated remote components should continue to work with all earlier versions of the SharePoint Add-in.
If you implemented a tenancy isolation system for your remote components, keep in mind that different tenants might be using multiple versions of your add-in, and a specific tenant might even have different versions installed on various SharePoint websites.
For a provider-hosted SharePoint Add-in that uses Microsoft Azure SQL Database or SQL Server, there are multiple methods for updating the database. To get started, see Upgrade a Data-tier Application.
