You are correct. Export the new certificate from the Exchange gui and include the private key.
On the ISA box import this file and key to the computer account personal store via the certificates mmc.
Edit the https publishing rule(s) and select the new certificate.

It is cleaner to stop and start the ISA Services when complete.

Thanks Keith

Can Explain to me about  : "Edit the https publishing rule(s) and select the new certificate."  ??

You don't import it on ISa, you import it through the operating system of the ISA Server using the certificates mmc.
When prompted, you select the computer account and import into the personal store - same as you would have done when you installed the original certificate.

This is basic ISA administration - right-click the existing listener and change the selected certificate from the expired to the new.

Apply the policy and job done.
