Which AWS EC2 instance should I use for v4 migration? Gives me error v4 needs 6GB at least

Hi:

I want to do a migration from ee v3 to ee v4.

When entered
./migrate.sh --dry-run --all

It gave me the message:
“We require at least 6 GiB disk space free
Disk space is too low to continue migration”

I currently use aws ec2 nano t2.

which instance should i use in order to make the migration?
