Moving report from Test to Prod Workspace through deployment pipeline error

Hello All,

I have 2 workspaces one for test and other for prod

I have already one report with same name in 2 workspaces. After moving to prod user requested for change so made those changes and replaced current one with changes report in test workspace. After that tried to move that changes made report to Prod again through pipeline, actually there was report before as I mentioned so it's like replacing only. But got error while deploying from test to prod below

The artifact couldn't deploy to target workspace. Try deploying the content again 

I deleted old one in prod and tried deploying from test to prod then it deployed successfully. But issue here I got is prod link changed which we sent to users before, they just want to access before link itself which we sent them before but not the new one 

How to make old link work now??

If any idea please help
