Hi, For the past day or so, I am not able to deploy a new version of my Azure Functions app. When I try to deploy using Maven, I get the following error: Status code 409, {"Code":"Conflict","Message":"There is an in progress azure migration for site 'xxx'. Please try again later." I get the same error when I try to change the app configuration from the Azure portal. Does anyone know what the issue may be? Any help is most appreciated!

Hi @MeraBills Admin Welcome to Microsoft Q&A! Thanks for posting the question. As per the error message "There is an in progress azure migration for site 'xxx'. Please try again later" it looks like there is already a customer initiated or backend operation that is currently going on and self-resolved by itself once the upgrades are completed. The 409 conflict is expected behaviour when there is already on going operation and you tried to perform another operation while the previous operation is not completed. If you have observed this issue for a long time then please share the CorrelationRequestId for the operation that you are performing along with the timeframe in UTC so I can check the backend logs and if the issue is due to the backend resource then I can engage my team to mitigate the issue.

@MeraBills Admin From the backend logs looks like there were multiple operations (customer initiated) at the same time causing the issue. The same can be verified from the activity logs of your function app. Can you try to perform any operation from the portal and it is successful and retry the operation?
