Basically you launch BlackBerry Desktop Software, create a back up of your current phone. Then when it is done, just inform your BBM members that you will be doing a device switch and will re add them, inform them to delete your current pin to minimize confusions on their end.
After you finish the security wipe from your old phone, it will be in the state where you had just bought it.
Now just connect your new phone, once it is connected to the BlackBerry Desktop Software, click on Device from the top left, then click on restore, but rather than simply clicking next, notice that the options says "All" change that to custom, and you will get the option of what components you want to restore.Only select Messages, contacts, SMS, MMS, BlackBerry Messenger, blackBerry Messenger Group, Browser Bookmarks
I can't remember the exact option list, but you get the picture. It is vital that you do not select options, application permissions, keystore certificates, trusted keystore, as those all contain certifications and permissions relating to your old phone which have nothing to do on the current setup and thus, might cause major slow down or errors on your phone
