First a quick note; this is a time sensitive procedure because Apple must be digitally signing the i OS system software versions in order for the downgrade process to work. you can also use the –Guest Credential if you have the credentials (get-credential) stored in a variable, in place of the –Guest User and –Guest Password parameters. if all vm’s have the same admin account or an Admin AD account, use that…Currently i OS 9.3.5 is being signed, meaning you can downgrade back to i OS 9.3.5 without an issue.
Once Apple stops signing i OS 9.3.5, then all users will have to stay on their current i OS release, or update to i OS 10.
This will install VMware Tools on the ESXi host and the total image size will be roughly 300 Megabytes.
