What are the different ways to move update set from one instance to another?
There are three different ways:
1. Transferring with an XML file
-> We can unload an update set as an XML file and then upload and commit it to another instance.
2. Transferring via update sources.

3. Transferring with IP access control.

How to transfer the changes which don't get captured in update sets?
Here are two ways:
1. Transfer record via XML export.
2. We can use GlideUpdateManager2 API script as shown below which allows us to capture any record in current update set:
var um = new GlideUpdateManager2();
um.saveRecord(current);
//current is gliderecord object, you can pass any other gliderecord object if required.
Note : This script needs to run in background script.

What is default update set? What its purpose? How it is managed by ServiceNow?
Basically Default update set is system generated update set. Only one update set can be the default set for any application scope.
To set an update set to be the default, you need to set the 'Default Set' field to true. When you set Default set = true, the following actions occur:
1. The update set becomes the default update set for its scope.
2. The system sets Default set = false for all other update sets with the same scope. This ensures that there is only one default update set for each scope.

What happens if we mark default update set as Complete/ignore?
System generates new update set with the name Default1 which will be used as default in future.
