translation of string in upgrade plan page

Hi there,
in the page where the user can proceed with the upgrade of the subscription there's this string:

Please enter information on the form below to process upgrade of your subscription from [...] To [...]

How to translate it? I can't find it Translation nor in Language Override.

Thanks.

Hello

Please go to membership Pro -> Emails & Messages, find the message item subscription_form_msg , change it to meet your need

Tip: To find a message, you can enter part of that message into the search box and the system will return the message items has that search text for you to edit

Thank you,
however, the string is subscription_upgrade_form_msg.
Have a good day.

Ah, Yes. subscription_upgrade_form_msg is the right message item to change. In general, you can search for message items base on content of the message. That would give you the matching items which you need to change
