Need Help adding Rb5009 To my system

Hello everyone i need some help without messing up my home internet.

At the moment i am using Starlink for my main internet provider. And have a crs326-24g-2s+ working as a Router and switch for my whole system. i have 14 mixed Hap’s and Cap devices in the house and about 7-8 rooms that have direct ethernet cables coming into the rooms from the CRS device. all my devices are controlled by capsman on the CRS device.

What i would like to do is to add a Rb5009 device so i can use that as a main router and then use the crs as a normal switch.

What i am thinking is to plug the starlink in ether 1 on the RB5009 and then Ether 2 to Ether 1 on the CRS or use a MikroTik XS+DA0001 dac cable to the crs and then keep all the other cables plugged where they were in the crs.

İs this possible ? if so what will my best option be without messing my whole system and making it work properly ?

Since they are 2 totaly different type of devices i guess backup of crs and restoring it on the rb5009 wont work, so how can i do the setup ?

Thanks in advance

Have you tried exporting the config, then manually editing it and importing back but into RB5009? This way you should be able to migrate easier than manually re-doing everything.
