Switched from Rithmic+Denali to SC Data, which caused a symbol change.

Now Sierra is downloading everything from the beginning.

Is this expected behavior?

Could I have just renamed the existing ESM5.CME.scid file to ESM25_FUT_CME.scid?

Is this expected behavior?

Yes. Sierra Chart stores the data based on the symbol.

Could I have just renamed the existing ESM5.CME.scid file to ESM25_FUT_CME.scid?

No. Different services have the data in certain formats and that is reflected in the stored files. Therefore, you can not rename (or copy) a .scid file for one symbol to another.
For the most reliable, advanced, and zero cost futures order routing, use the Teton service:
