If you have not played using your Ubisoft Connect account yet, when you log into a Ubisoft Connect account for the first time while playing as a guest your progress will be directly linked to your account and you can continue enjoying Resurgence as you were.

However, if your account has already been used in Resurgence since the launch, then the progress on your guest account will be lost when logging into that Ubisoft Connect account. In the case that you decide to keep the progress on your guest account despite having already used your Ubisoft Connect account on Resurgence, make sure to log into a brand new Ubisoft Connect account directly while playing on your current guest account.
