Reporting services 2008 reports connection to azure sql database

Due to the end of support of sql server 2008 R2 we are planning to move the database to azure as a paas service (azure sql database). Right now the application server has reporting services 2008 R2, for now it won’t be moved to the cloud or upgrade his version. The users create the reports, then they upload them to reporting services and generate the desired information, My question is this: since azure sql database uses the latest version of sql server do the users or myself have to redo the reports in a newer version of report builder or visual studio data tools, or the reports will work the same way and the only thing I have to modify is the data sources.
