I'm updating from 4.2 -> 5.1 and according the documentation that must be done through 4.3 or 4.4 due some database change.
So I updated the system to 4.4.1.30 (latest). I have two clusters running 9.4.18. Now the one of those is stuck 'adding cluster'-state similar as https://www.dell.com/support/kbdoc/en-us/000211295/powerscale-insightiq-not-updating-new-cluster involved version 4.1.4.57. System is still collecting data from both clusters.

I cannot now export the second database -for update to 5.1. is there a command line utility do export or is the step 4.3/4.4 really needed i.e can I use export from 4.2?
