# existing and fully operational FusionBPX server.  I am by no means an expert and this script is not intended to be
# super advanced in anyway.

#
# SOME THINGS TO NOTE BEFORE WE PROCEED:
#
# This script will automatically check your system to ensure it is supported and that a source installation
# of FreeSWITCH actually exists.  The traditional path ($fs_path) is used for this check.
# Additionally, there are some files we will need from the FusionPBX installation folders, so if you don't have
# them this script will fetch them for you and place them in ($fpbx_path).
#
# NOTE:  If the FreeSWITCH path is not detected this script will not continue!!!
#
# VERY IMPORTANT:  IF YOU HAVE NOT BACKED UP YOUR SYSTEM, DO SO NOW!!!
#
# I take no responsibility for a failed system as a result of using this script.  If anything should go wrong
# a proper backup should be easy to restore.  If you proceed without taking a backup, YOU ARE FULLY RESPONSIBLE!!!

# Congratulations, you have just completed an in-place migration of FreeSWITCH
# from a source compilation to a package install.  Some final things to note:
#
# 1.  Log back into FusionPBX and check to make sure ALL modules have started and are running:
#
#     ADVANCED >> Modules
#
# 2.  This is optional, but I chose to reboot the server at this point.  
#     When the server comes back up, login into FusionPBX and check the Sip Status page to make 
#     sure your profiles have restarted.  That’s it, enjoy!
#
# 3.  And to wrap-up, you might consider bringing your system up-to-date via ADVANCED > UPGRADE.  
#     I did run into some issues with the new changes that had been made with MOH, however, all 
#
#     If this is the case for you, follow the instructions provided by a member of the #fusionpbx 
#     IRC channel:  http://pastebin.com/fHw0wDjb 
#
#     If you get this error when placing calls to *9664 to test MOH, then simply restart FreeSWITCH:
#     < [ERR] mod_local_stream.c:814 Unknown source default >
