Downtime occurs during installation.- Thks so much your help
we have already using Exhcnage Server 2019 RTM version, and over 6000 email address users. Your reccomment was Exchange Server 2019 and new installation process right? After backup and install new Exchange Server 2019 with last **bleep** then restore old email and data to new Exchange Mail Server ? What's happen will be that time, it is compatible Exchange 2019 RTM ver and Exchange 2019 only?
