Container migration between Parallels Virtuozzo Container (PVC) nodes registered in Parallels Business Automation - Standard (PBA-S) fails with the error:

 transport not specified


Source and destination nodes use different protocols: VZAgent 2.5 and VZAgent 4.6. Migration between nodes with different protocols is not allowed.


You can either upgrade the node that uses VZAgent 2.5 to the latest PVC version or install PVA 4.6 Agent on it in accordance with the following KB articles:

How to Install/Reinstall/Upgrade PVA 4.6 Agent to a PVC 4.0 HW Node

How to install/reinstall/upgrade PVA Agent on PCS 6, PSBM 5, or PVCfL 4.7 HW Node

Parallels Virtual Automation builds, releases, and supported virtualization products

Note: that after the PVA 4.6 Agent installation on the node, you will have to re-register it in PBA-S setting VZAgent 4.6 as a protocol.
