We are scheduled to be switched over to OCI next week. Is there any issues I should be aware of?

We were just switched a a few weeks ago. I think we’re a fairly large customer and we didn’t notice anything. We did have them schedule it for a Friday night so that we had a couple of weekend days to test some things out. We also thought it might help by having our regular jobs running all weekend on the DB.

Will we need to generate new security keys for integrations?

We didn't have to do anything around tokens, authorizations, etc. on our change. Didn't even really notice. Might want to light a few candles for the internet deities though - just to be safe.
