Windows vCenter 6.5 Update 2c PSC/VCSA

Dear Communities

I am finding lots of information about this so was hoping I could get some solid information. I have a windows vCenter 6.5 Update 2c with an external PSC. Are any of the following possible:

- Migrate the External PSC to embedded into the existing Windows vCenter 6.5 Update 2c

OR

- Migrate from the External PSC and existing Windows vCenter 6.5 Update 2c to a VCSA (with Embedded PSC) of the same version (6.5 update 2c)

Thank you
