After performing SDX appliance restore according to edoc:
https://docs.citrix.com/en-us/sdx/current-release/configuring-management-service/backup-restore.html
SVM's network configuration is not restored

For SVM Network configuration restore:
As not restoring network configuration on SVM is a by-design behavior, if you'd like to apply the old network configurations such as IP, Netmask, Gateway, DNS etc, please find the configuration from back up files.

Note: Please make sure that old network configuration is still reachable on your network before you apply the change.

Extract the backup files to a folder naming as "backup", then try find the configuration from resources.xml.
/backup$ xmllint --format resources.xml | more
Then find the settings from the following elements
<current_hostname JSON="{ &quot;hostname&quot;: &quot;ctxsdxhost01&quot; }"/>
<current_timezone JSON="{ &quot;timezone&quot;: &quot;UTC+0800 CST Asia\/Shanghai&quot; }"/>
…
  <sdx_network_config JSON="{
&quot; dns&quot;: &quot;10.0.0.1&quot;,
&quot; gateway&quot;: &quot;10.1.2.3&quot;,
&quot; actual_network_interface&quot;: &quot;0\/1&quot;,
&quot; svm_ipv6_address&quot;: &quot;&quot;,
&quot; additional_dns2&quot;: &quot;&quot;,
&quot; additional_dns1&quot;: &quot;&quot;,
...
&quot; svm_ip_address&quot;: &quot;10.1.2.153&quot;,
&quot; gateway_ipv6&quot;: &quot;&quot;,
...
&quot; xen_ip_address&quot;: &quot;10.1.2.253&quot;, ...

Problem Cause

SVM doesn't perform Network configuration restore by itself to prevent losing connectivity to the appliance after restored to an invalid network configuration.
But the old SVM network configuration can be found from backup files.
