Facebook – Can a user with added role of admin invite friends to that fan page

I was just researching this exact same question for a client. I work primarily with authors and speakers, and this question comes up a lot. Here are the key things to note.

When you migrate a profile to a page:

• you do lose the old profile. You have to create a new profile for your personal use. But if the idea is to clean up the profile, starting with a clean slate isn't a bad thing!
• only your profile pictures and friends/subscribers are transferred over to the page. So, backup your content if you have any interest in saving it. It won't be accessible later.
• other than the new likes and a profile picture, your new page is blank. Once again, not a bad issue. Just start creating content. At least you'll be off to a great start with the following.
• if your profile is the admin for any groups or apps, assign new admins before you migrate.
• if you have a username specified for your profile (otherwise known as a "vanity URL"), it will be applied to the new page instead. FB does not allow you to change the username of a page with more than 200 "likes," so depending on how many people are friends, you may not be able to update the username of the page.
• from what I can piece together, the name of the new page (the page title) is based on the profile name. Therefore, Joe Schmoe's profile will be displayed as "Joe Schmoe" for the page title. At least that's my guess. So, if you want a different title, change your profile name before you update the account. The first name could be "Joe Schmoe's" and the last name "Awesome New Facebook Page." You get the idea. I have to admit, I have not tried this out yet, but my guess is that it would work. Otherwise, to change a page title, you have to put in a special request with Facebook, and they're not very responsive about it.
• the newsfeed of your new page will be blank because you haven't "liked" any other pages yet.
• some people may be put off by becoming a fan when they thought they were your friend (think old high school classmates, family members, etc.). So, anticipate a drop-off in "likes" soon after the conversion.

Know that making a page is definitely the right answer. You need to be in conformance with Facebook's terms of agreement, otherwise, you risk them shutting your account down. But there are other reasons for it too. For instance, Google indexes pages, but not profiles. In addition, pages allow much more functionality than profiles do, including adding apps for a mailing list, creating events, etc. I hope this helps!

Yes, he can. His friends will become subscribers to the new page.

When you convert your personal account to a Facebook Page, we'll transfer your current profile picture and add all your friends and subscribers as people who like your Page. Your account's username will become the username for your Page, and the name associated with your personal account will become your Page's name. If you want your Page to have a different name, consider creating a new one.

No other content will be carried over to your new Page, so be sure to save any important content before beginning the conversion:

1. Download your timeline information. You can download a file that contains all of your sent and received messages and all of the photos and videos you’ve uploaded to Facebook.

2. Appoint a new group admin to any groups you manage. You'll be unable to manage groups once the conversion begins.

When you're ready, start converting your personal account to a Facebook Page.
