Need documentation for Cisco FTD 2110 to FTD3105 migration on same FMC

[FirewallGeek1]

I am currently in the process of migrating our existing Cisco FTD 2110 device to a Cisco FTD 3105, which will still be managed by the same Firepower Management Center (FMC). While I’ve already searched through Cisco’s official documentation and performed a thorough search on Google, I have not yet come across any comprehensive or specific resources that cover this migration process in detail.

To clarify, I’m looking for any step-by-step guides, best practices, or detailed documentation that outlines the procedure for migrating the configurations, policies, and any other necessary components from the FTD 2110 to the FTD 3105. Additionally, insights into any potential pitfalls, troubleshooting tips, or performance considerations for such a migration would be immensely helpful.

If anyone has gone through this process before or can point me to any official or community-based resources, I would greatly appreciate your assistance.

Thank you in advance for your time and help!

I forgot to mention that the current version on FMC is 7.3. This link works for 7.4 as I do not see "migrate" option on current FMC. In this case, would I need to import the device configuration from existing FTD and then import into new FTD (both are already in FMC). Any special considerations. Thank you
