Bad news. As you suspected the Acronis software did not see any of my drives after I installed the new raid drives and inseted my old slot 0 raid dirve in slot 3 and booted to Acronis.
I removed the new raid drives and re-installed the old raid drives ( in their original slots) and rebooted. The system started but the Raid Web server popped up with an error on the drive in slot 0 and automatically started a rebuild.
After about 10 minutes the system crashed (blue screen). Upon rebooting again both drives were marked offline and I couldn't do anything on the subject server to get either of them to boot.
Both drives are accessible when installed on a Windows 8.1 machine i use for utility work so there is no apparent data loss on the drives ( I also have full data backups) but in order to use the larger drives on the server I started the 2 day clean install process of the entire system and applications.
