# How can I migrate from an older Cathexis Vision release the latest available release?

|| **Question**

How can I migrate from an older Cathexis Vision release the latest available release?

| **Answer**

You would need to add CCVM *Cathexis camera version migration* licenses for the number of IP cameras loaded on the site/server. 

If the server migrates from CathexisVision 2016 to 2018, the server would need two years of migration licenses for each camera.

Please contact support@cat.co.za should you be upgrading the product and are unsure of how to do the upgrade.
