Migration from .NET6 in-process to .NET8 isolated

Disclaimer: this is an experimental project and should not be used as-is in production

The goal of this project is to experiment with the migration of functions in .NET in-process to .NET8 isolated using deployment slots as described in this migration guide

Deploy the infrastructure

azd provision

Deploy the function in .NET6 in-process to the production slot

Deploy the initial version of the Function App written in .NET6 to the production slot.

A sample code was provided in the ApiInDotNet6InProcess directory.

func azure functionapp publish $FUNCTION_APP_NAME --dotnet

Test the Ping function (on the main/production slot) and ensure it returns PONG .NET6.0.

Deploy the function in .NET8 Isolated to the staging slot

Deploy the migrated version of the Function App written in .NET8 to the staging slot.

A sample code was provided in the ApiInDotNet8Isolated directory.

func azure functionapp publish $FUNCTION_APP_NAME --dotnet-isolated --slot staging

Test the Ping function of the staging slot and ensure it returns PONG .NET8.0.

Swap slots

az functionapp deployment slot swap --name $FUNCTION_APP_NAME --resource-group $RESOURCE_GROUP --slot staging --target-slot production

Test the Ping function on the production slot and ensure it returns PONG .NET8.0.

Delete the resource group

Don't forget to delete the resource group once you have finished testing the migration with slot swapping:
