Problem with vlans merging one core to another core

So we have a COLO core in the 10.20.9.254/24, and we are moving the entire server farm attached to this core to our corporate MDF, which has a core of 10.11.9.254/24. I want to change the vlan IDs to the COLO segments, and merge to the CORPORATE core.

I beliwve this will work, just wanted some of the guru's to check my details.

So 10.20.0.0 ---->  10.11.0.0  changing the vlan id by adding 200 to it's current value.
