upgrading the superblock version

Hello.

I'd like to know if it is possible to upgrade the superblock model version of an array, from 0.9 to 1.0 for example.

Theoretically it should be possible, I think. What would be the safe steps to do it?

I imagine something like:
- zeroing the current superblocks in all the array disks;
- (optionally) assembling the array in "build" mode, ignoring superblocks;
- updating the superblocks using the desired version.

If that isn't possible, then:
- zeroing the current superblocks in all the array disks;
- creating a new array with those disks, using the desired superblock version and --assume-clean;
- would this lead to the loss of the partition table inside the array?

Has anyone done such a thing?
How should I proceed?

Thanks,
Vasco.
