Performance Data Exists database contains old performance data

Hello Tech Pro,

When I am building a database engine, I ended up with a weird error message. This error message gives me some options to fix this error. However, nothing seems to work for me. I need to do this job before this weekend. I have attached the image of the problem; please do help me to fix the problem. Thanks a lot. 

Performance Data Exists

This database contains old performance data. Would you like to discard the old data and start fresh?

Select “Yes” to delete the existing performance data and begin a new collection. Deleting the existing performance data may affect or overwrite any dependent data you’ve defined in the Server Consolidation, Microsoft Private Cloud Fast Track, and Azure Migration features.

Select “No” to append new data to the previously existing collection.

Select “Cancel” to make no change and return to the console.
