This question comes up often because the installation of APM 10.1.x, 10.3.x, and 10.5.x TIM is supported on vMTP 10.6.
Note: Installation of APM TIM 10.5.x is supported on VMTP 11.0.1. At this time no APM TIM release supports vMTP 11.0. See https://www.ca.com/us/services-support/ca-support/ca-support-online/knowledge-base-articles.tec1241257.html for more details on APM-MTP Compatibility.
Can I upgrade directly from vMTP 10.6 to 11.0.1?
APM 10.1/10.3/10.5 with vMTP 10.6
No, this is not supported for doing this at this time. Note that the Vertica release also changed as well which would impact this particular upgrade release combination.
