Integration and with owner of Team/Projects

I am currently an added member of Asana, collaborating across partners external to my organization. We are embarking upon buying our own version, but as the Project Manager, I am expected and need to start building out more of what is currently in the works to the project I am a team member of. Since I am invited to this, will there be issues when my company does upgrade to use Asana, or would I be able to remain a member and have the ability to continue using this as a team member and PM seamlessly? I want to anticipate and understand how much “double work” I might be in for!
Thanks in advance
