This is step 15 of performing a major upgrade from Enterprise Server 7 to Enterprise Server 9.2 or higher. (See a list of all steps)
Purpose of this step
Upgrade any layout templates or article templates that are used to Adobe version CS6 or CC.
Step to follow
Convert any InDesign and InCopy templates that you use to the new version of InDesign and InCopy by opening the file and re-saving it.
Note: Once layouts have been saved to the newer version of InDesign, they cannot be opened in a previous version without converting them to .IDML format. Doing so will remove all links to any placed database files.
