# Export-VCDB.ps1
#
# Version:  1.0
# Auhtor:   Arnim van Lieshout
#
# This script will export your vCenter database objects to several .xml files.
# These files can be used in combination with the Import-VCDB.ps1 script to recreate those objects into another vCenter database
#
# I've put every step in a seperate function, so you can easily select the steps you need in your environment
#
# Known Limitations:
# - Datacenter folders are not supported
# - Resourcepools are not supported
# - Objectnames used in vCenter must be unique, because the name is used as a unique reference
# - Cluster EVC mode is not supported
#
