Not sure, if it has something to do with managing attachment,font size etc you may use system properties.

Hello Harsh,

Please find below information related to instance Re-sizing.

 Instance resizing :
- An instance resizing moves the instance to higher sized database nodes. Note: Node addition is a continuous process that is controlled dynamically in our cloud to improve the performance of your instance.

Q. Can I clone or upgrade or my instance during or after my instance has been moved?
A. Clone service will not be available for at least five hours before the start of the move and two business days after the move is complete.

Q. Where can I go to find more information?
A. Please review this Knowledge Base article (https://support.servicenow.com/kb?id=kb_article_view&sysparm_article=KB0958914) for additional details around this automation.

Q. What happens to my instance data on the previous hosting database servers after my instance migration is completed?
A. After an automated instance migration is successfully completed, an automated process executes a post-instance migration cleanup activity, which includes retirement and logical deletion of the database instance. This is completed approximately two days after the successful migration. For clarity, data from backups in the prior hosting location will cycle out in accordance with our backup policies.

Here's what we need you to do :
• Review the date and time of the instance resizing/migration. If IP addresses are listed above, please review and whitelist if necessary.
• Please update this change (CHG- which has been raised on Support portal) with any questions you have about this maintenance activity.
• If you need to reschedule, update this CHG with a request to reschedule within one business day. Please include a preferred maintenance date and time with your request and we will work on honoring your request.

Thanks,

Sampat
