But before applying below plan, i would like to consult to the community. I wish to minimalize down-time of mail service (Product is MailEnable). Also i have 3 weeks to solve this issue. Last resort is 8 hour downtime on weekend-midnight.

Use a migration tool like Zerto for this process to minimize potential downtime.
