Leaving Hubspot – Share things you wish you had done (or later realized you didn’t need to do!)

As the title states, I am leaving Hubspot in a couple of months. We used most elements of it but our organization has shrunk and we no longer need features like the Deals module, etc. I'll be heading to Constant Contact (I think) for 1/4 of the price.

• Apart from getting my contacts and lists, what else should I export?
• What did you forget to do that you wish you had?
• Whats the best way to export Deal info?
• What did you leave behind and it didn't matter?
