Upgrading from Legacy Releases

Upgrading and Migrating from Legacy Releases

If a direct upgrade or migration from your current release is not supported, you can use the following process:

  • perform a direct upgrade to an intermediate release using either the Unified CM OS Admin interface or the Cisco Prime Collaboration Deployment (PCD) Upgrade task

  • perform a migration from the intermediate release to the current release using the PCD Migration task

Find your starting release in the table below and use it to identify the intermediate releases that you can use as steps in the upgrade and migration process. After you have identified the intermediate release, use the links in the steps below to find the documentation for that release.

If your starting release is not listed, it may require an upgrade to more than one intermediate release. See the "Supported Upgrade Paths To/From Table" at http://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucm/compat/ccmcompmatr1.html#pgfId-391518.
