I have been using brightmail since a few year ‘s now and in this few years, I have never thought of upgrading it to a newer version. But a few days back when I opened up my Brightmail it pop out a link to update the software. The reason why, I am worried is, I have all my contacts and important mails stored in it. So while updating there might be a problem which may cause me to lose my data. Can someone please tell me the update procedure? And also the steps that I need to take in order to back up the contacts and mails (just in case there is a problem).
