There ar several good ways, but this is what I recommend:

- Install the new TeX and use it for a while
- When you're satisfied:
	- uninstall the old TeX i-Package
	- re-run the new TeX configuration phase (this repairs the CLI  
setting that was removed by the old TeX removal)
- When you're unsatisfied because something is missing an dwill not  
be fixed soon:
	- re-run the old TeX configuration phase, which switched the CLI  
settings back.
