Moving to a new UPS

Question

The UPS where my VNXe is telling me it is failing. Currently, both power supply are connected to a single UPS. I wanted to power my VNXe using 2 separate UPS going forward. I am hoping that I don't need to schedule any downtime to do this. Since there are 2 power supply, am I correct in assuming that I can unplug one power supply, say DPE Power supply B and plug it to a new UPS without powering down the whole DPE? After a few minutes, I will unplug the Power supply A from the old UPS and plug it to another new UPS. Will that cause any problem?

Thanks

Yes, the Power supplies are shared and redundant. If one fails or you move it's power source, the surviving one provides power to both SP's.

When you move PS-B to the new UPS, wait until any fault conditions (leds) normalize then do the other. As you've said, a few minutes should be sufficient.
