while using prefect 2.0 beta version i was creating my multiple deployemnets using the following code and then running prefect deployemnt create {name of the file } and my multiple deployments were getting created but now there is not any option to create muliple deployments and neither ist specified in the docs and my previous deployments are shown deprecated . please help

Did you check the links shown on this deprecation page? It shows the instructions on how to migrate

there isnt any info about creating multiple deployments

It could be because you created this deployment in the beta version. Could you try to upgrade to 2.0.1 and deploy again? This error shouldn’t be there anymore
