My neighbor moved away and gifted me with this plant. The flowers are pale violet, and turn white as they age.

There is some cold weather damage that I'll remove as I re pot.
I don't know what type of medium, if any, is there now. I typically use bark on most of my potted orchids. I have some new plastic pots for this.
Any advice on how to split this, or links to posts or videos?
Are several small plants better that a few large plants?
We are coming up on some warm weather forecast, so I think this is a good time. Certainly little chance of severe cold now (Central Florida).
Any tips or pitfalls are appreciated. Thanks,
CB
