Step 1: Export "Organization" goals from Import/Export Goals tab.

Step 2: Filter the goals that you are looking for to archive and remove all the other goals.

Step 3: Change the status from 'Active' to 'Archived' under the Status column. (Shown in the screenshot below)

Step 4: Upload the file again.

Note - Please be noted that you would be able to archive only the individual goals through this method and not the Department/Organization goals. These goals need to be archived one by one manually. We would recommend not to upload more than 250 goals at once.
