Nice :-)
I assume that it is not possible to move to newer one?

It depends on what commands do you have?
Yes, it would be best to use load command to get the data via serial
line, store it in RAM and then flash it on persistent memory.
How do you access NVRAM? (Is it really this memory - not some Parallel
NAND, SPI-NOR, OneNAND)?
If it has a custom driver ,then you may want to look for 'cp' or other
command.
