Grounding ungrounded outlets

Hi all!
Can I ground an ungrounded outlet feed from a
sub-panel by running a ground wire from a
grounded outlet which is feed from the main panel.
(Note the sub panel originally was the main before someone installed a new one.)

You can run a ground wire to that ungrounded receptacle, but the ground wire should come from the bonded ground bar in the subpanel, the same panel the power comes from.

The panels are installed with in 10" inches from each other using 1" metallic rigid conduit. Would that make a difference. Thanks for the reply!

By code the new ground can be connected to the main ground of the source panel at any suitable place within five feet of the panel. Best to go into the panel but connecting to the nipple between the panels would probably be code compliant.

There should be one or two grounding conductors coming out of the main panel to go to ground rods or a water pipe. You can connect the new grounding conductor to any of those w/in 5' of the panel.

Your new grounding conductor needs to be green insulated wire, not bare copper.
