Currently we are on older HSPc, but meant to be upgrading to PBAs. In the mean time I am trying to audit all the plans in our system as we have customers on plans from 6 and a half years ago. I need to know if there is a way to do a mass upgrade between plans, as the "Upgrade Subscriptions" under "Product Manager" -> "Hosting Plans" only allows you to upgrade the subscriptions to the latest version of that plan, not upgrade them to another new plan (they are on a plan listed as "Unix Starter Hosting", still on our Linux servers, and I am trying to upgrade them to our "Linux Starter Web Hosting" plan). I do not want to go through a few hundred subscriptions and upgrade them manually, and customers would generally find it hard to go through the process without issue, as they have trouble doing simple things in Plesk. If this is not the correct forum, please move it to the correct one. Thank you.
