HI everyone,
Hope you can help. I am still stuck in the sql upgrade project. I upgrade SQL 2014 to 2019. I was forced to uninstall reporting services with no choice during the upgrade, so I add the reporting service (from the 2019 cd) and reconfigure it by the SQL Reporting Services Configuration Manager. I did point it back to the original reporting and reporting tempdb database, restore the key... I tried the report server link itself and I could see all the custom reports there without any issue. I assume the reporting services is in good shape.
I have an IIS server with a 3rd party program to retrieve some reports from the application. It generates the following error (see the attached pic) regarding to reporting services 2005. Do you know what that error is? I am not a developer so I am not good at coding. WOuld it be any chance the 3rd party app still using some reporing 2005 coding which is not compatible with reporting 2019 (I am just guessing so please do not consider it if I am wrong).
I really run out of clues on this.... Hope you can help.
Thank youl
Takami Chiro
