What is the practice to update Pharo 9 image during development

Hi

What is the good practice to update Pharo 9 images that are being released
while I am developing code for my application.

Currently make a fresh install, reload all required packages (Seaside,
Magritte ...), reload my code, configure blah blah ....  is there a better
way

cheers,
Sanjay
