  • Administrator access to the following:
    • CMS instance (to perform Synchronization)
    • IIS instance (to rectify timeout errors)
    • Filesystem where CMS is located (to backup existing data)


The following recommendations are suggested when conducting a Schema Synchronization in the CMS:

● Before begining any Synchronization activities, backup the %site root%/xml folder as a precaution.

• Ensure that no users are working within the CMS and that no publishing or automated tasks are being run.

• Synchronize in groups of no more than 20 xIDs at a time.

• If CMS becomes unresponsive during the Synchronization or if recycling the application pool should become necessary, the following steps should prevent the issue from repeating:

■ From within the ASP settings of IIS, Increase the Script Time-out property for the CMs instance:

○ IIS Manager > CMS Site Instance > ASP

■  Increase the default Time-out to improve Schema Synchronization time-outs:


Script Timeout ASP


■ If you still receive time-outs after implementing the above change, try performing a Check-Out on the pages in question prior to beginining the Synchronization.
