When I ran

compare database aim with aim_live to file upgrade.prg

I get a message coming up saying

Production index file not found for 'T1'. Do you want to proceed

I say yes and did not seem to get the upgrade.prg, looked for via a search on my drive

I have no idea what the message means.

Can some please explain to me what this means.

I had a database aim which i copied to aim_live then imported my vfp database from my current live vfp system then ran this code
