ESP32-WROOM-32 instead of ESP32-WROOM-32D

Due to component shortage, I am considering replacing my WROOM-32D With a WROOM-32, i.e. an older version of the WROOM module.
Is this possible without hardware changes or Arduino SW changes?
Thanks

Yes, probably rev 1 chips in both. If you were using E series then you would have to consider rev 3 to rev 1 differences.

A bit of feedback in case someone has the same question.
The swap went fine but I had an interesting challenge with my usb connection.
The 32D seems to drain slightly less power at start. I suspect it peaks when powerung up the wifi. The 32 pushed my design over the edge causing dropput of my CH340 modem and I got a regular dropout of the usb port.
Powering the board from a separate supply fixed the problem but I need to go back to the 32D in the future. Perhaps the 32E is even more efficient in this regard?
