Migrating Google Instance, Change Zones from Singapore to Indonesia

I currently have 3 instance with google cloud in zone Singapore, i want it to change to Zone Indonesia ,

is it possible migrate without downtimes ? if not, how long of downtime estimate ? one of the instance is Database MySQL with over 250 GB space. please advise.

and please only those with experience in migrating zones to apply. its very important since the site must not be down if possible, or at least with minimum amount of time.

due to sensitivity of data it may require you to screen record what you did , or share on zoom live what ur doing .
