Keeping tech access to conquered race tech after migration should not be possible

[Badok]

So to reiterate: You capture a city of another race. Now you can:

1. Raze it - no tech.
2. Migrate it - no tech.
3. Absorb it - yay tech.
4. Absorb and THEN migrate - yay, then nay.

Do I understand it correctly?

Almost, once you have unlocked the Tech Tree you do keep it so it's more like:

• Raze it - Nay
• Migrate it - Nay
• Absorb it - Yay
• Absorb then Migrate - Yay (We stole your stuff and then removed you.)
