Adding an existing field

[N8Laskey]

Just to clarify - if you add an existing field to a form (like dragging it from left box to right box) is that considered 'customization' ? Our admin tells me that doing this is customization and that it will impact upgrades - I do not believe this is so - thanks!

As a sysadmin, I don't see where moving an existing field from within the same form would affect performance, as long as all you're doing it moving it.  as for upgrades, if make it in Prod, once you clone, it should get cloned down to your sub-prod instances. as for impacting upgrades, it will not

Adding an existing field to a form in ServiceNow is considered a form customization. However, it is generally considered a "light" customization and should not typically have a significant impact on upgrades.

When you add an existing field to a form, you are simply modifying the layout of the form, and the field is already present in the system. This means that when an upgrade occurs, the field should still be present and should not be affected by the upgrade. However, it's important to keep in mind that during an upgrade, ServiceNow releases could include updates to forms and fields, which could affect your customization. It is advisable to keep track of any customizations made to the forms, and test the forms after an upgrade to ensure that customizations are still working as expected.

It's also possible that your admin is speaking about a different kind of customization. There are different types of customizations, and some are more complex than others, and can have a greater impact on upgrades. Such as custom scripting or creating new fields, modifying core system tables, etc.
