Description of problem:

Warm migrate win 2008 sp2 VM: mtv-func-win2008 (PowerShell: 1.0) with static ips from vCenter7 to ocp cluster with preserve static ip: on, after migration the static ip settings no longer existed.
Check the network script: 9999-network-config.ps1 execution log, hit error: "Missing expression after unary operator '-'."
The script work well on win 2008r2 (PowerShell: 2.0), need modification for PowerShell: 1.0

Version-Release number of selected component (if applicable):

MTV 2.8.5-9(IIB: 979366) with CNV 4.18.5, MTV 2.8.5-7(IIB 979184) with CNV 4.19.0

How reproducible:

100%

Steps to Reproduce:

1) Create windows 2008 sp2 VM with 3 interfaces: 2 with static ip settings, 1 with dhcp

2) Create warm migration plan to migrate VM from vCenter to OCP cluster, preserve static ip: on, Mgnt network -> NAD mybridge, VM network -> Pod network, VMMCDB112 -> NAD mybridge2

3) Plan executed successfully, check the conversion pod log virtio_win: /usr/local/virtio-win.iso", after migration: the dhcp -> pod network, get the pod network ip address and can ping outside, check the conversion pod log as below, more details in attached file: v7-us-vm-1986-fr2pv-virt-v2v.log

4) Static ips which map to NAD bridge networks are no longer existed,  check the network script log on target VM, it's hit error: "Missing expression after unary operator '-'."

5) Get the NetworkAdapter by Power Shell command line, the virtio ethernet adapter driver work

6) Rerun the script: 9999-network-config.ps1, get the error: "scripts is disabled on the system", this is because the Set-ExecutionPolicy is Restricted by default in win2008 sp2.  Change the Set-ExecutionPolicy to Unrestricted to allow the script exection.

7) Rerun the script: 9999-network-config.ps1, get error "You must provide a value expression on the right-hand side of the '-' operator", the power shell version: 1.0.
