Moving from Free to Standard with Jira Management Software and Task Manager

Question

I'm currently working with the free version of Jira Management Software and want to move to the Standard option due to the email notification limitations. I know moving from the Free to Standard won't result in any data loss, as it's basically putting a Credit Card on it and certain added permissions becoming available, but, what about the Jira Task Manager?

These are the specific inquiries that I have: 
1) Will both platforms (Jira Task Manager and the Management Software) become a single one or they remain separate? 
2) Will both platforms be paid separately through separate invoices or it becomes a single invoice for both?
3) Will data on both platforms remain untouched simply by upgrading to the Standard version of the Management Software?

I don't know those kinds of details. I would suggest contacting Atlassian Support for those questions.

Actually, the "Restore from Jira Cloud or Server" section states "Import your data first. Importing your data file will overwrite all data (except for users and groups) in your Jira Cloud site."

If I export a backup for the Help Center project on Jira Management Software, and import it on the empty Help Center on Jira Management Software of the second and soon-to-be main account, will it affect ALL Jira data, or solely the Jira Management Software (help center project so to speak)?

Oh that's fantastic! O.o 
I read through the process but couldn't find confirmation that this will only influence that specific project, and won't touch a second project (that's not related to management software but something else, but still under the Jira Software platform).

Based on what I read, it shouldn't, it would literally add that specific backup into what you're running right now, without deleting things that are there (unless they are updating said values lets say), but it's kind of a big step so 99% sure isn't enough? haha. Can I get confirmation that this will only add the configurations and data (tickets, attachments etc) from the Help Center we were running into the new empty one, without touching secondary projects that have nothing to do with Help Center?
