Moving from ROM to another does need data deletion

[bmsbms16]

Hi
I have a Redmi 5 plus on the official MIUI 10 global ROM
I would like to download xiaomi.eu rom
What do you advise me is stable or beta
If I convert to xiaomi.eu I need to delete my data.
And the second question
And if I download xiaomi.eu miui 10 then I want to update to xiaomi.eu miui 11 do I need to delete my data?

Go straight to miui 11 stable, yes delete data for clean install and no bugs

Thank you
I asked because MIUI 11 has not yet come but I said I don't want to lose data twice.
So wait for xiaomi.eu miui 11 and install it

Wipe data is not enough when coming from official Global/China ROM:

…
ROMs for devices with locked bootloader:

• Unlock your first bootloader here http://en.miui.com/unlock/
• Install TWRP via Fastboot mode, then install our ROM

• fastboot flash recovery twrp.img
  fastboot boot twrp.img

• TWRP Recovery Zip DOWNLOAD or TWRP.ME
• FORMAT /data partition (NEVER wipe System or Persist!)
• Copy our ROM to the internal storage
• Install our ROM
• Reboot
• done

OK , but Miui 11 has not been updated yet and ask if i have flashed xiaomi.eu miui 10 and then added miui 11 update to my device do i need to erase the data until i move from miui 10 to miui 11
