Cannot upgrade from 3.5.0 to 3.7.0

[danhngo-lx]

Hi, I'm trying to upgrade Litmus from 3.5.0 to 3.7.0 but having this error:

litmus-chaos-center-server-59ccf69588-rcfzb       0/1     CrashLoopBackOff   1 (5s ago)    17s

The logs of the server:

I suspect the reason for this error is because I dind't enable upgradeAgent:

upgradeAgent:
  enabled: false

But if I change it to true, the upgrade-agent cp pod cannot start:

litmus-chaos-center-upgrade-agent-cp-2-69jxn      0/1     ImagePullBackOff   0             7m15s

It's because the image is missing:

How can I do the upgrade in this case? Any help is appreciated.
Thank you!

Hello, I have the same issue when upgrading from 3.6.0 to 3.7.0, the portal server crashes with the error control plane needs to be upgraded from version 3.6.0 to 3.7.0.
