We are in a exchange migration process and we are rehydrating our mailboxes. We currently have one EV server that is virtual. If I want to clone the server and create a new virtual server so we can have a second system to rehydrate from is that doable? Will the archives still be linked to the exisiting exchange environment?
It's a strange idea ;)
Have you try to launch many (maybe 5 or6) instances of the wizard in same times for rehydrate your mailbox ?
Maybe you need to had some CPU and memory at your VM ... but I do it for import PST files by the EV wizard ... then why not do it for rehydrate ...
I may even suggest migrating the archived data independant of the mailbox and to save you a bunch of hassle, including the necessary resources (and time) to "rehydrate" all that data. If you have a Journal ... there is another concerns.
