I'm migrating a bulk of PST files located under a file server partition to EV 12.5, for that I'm using "PST migration: Locate and Migrate" everything is happening smooth for the small PST (< 4 GB) however I'm facing a failure with the big PSTs ( > 8GB) the migration is failing with error "could not copy pst file the specified network is no longer available" even though the location is totally valid!!
Any recommendation for migrating those big PSTs and are there any settings I should tune on EV to make it work?
thank you for your valuable feedback,
it's too many more than 200 PST, do you think could be causing it to disconnect or timeout (antivirus, firewall, ...), I really need to find a way to move those PST and can I trace what's causing the issue to happen?
I am not sure which version you are using, but for the latest releases you can use 'scripted migration'. This allows you to copy the PST files to a central location, and then use a script to define which PST goes where, assign retention etc.
This is the same for 12.5, but check your documentation folder for the version specific configuration.
so the scripted migration is the only way to migrate big PST files? and why it doesn't work using "Locate and Migrate"?
Has anyone been using this method to migrate big PST, there has to be a way to make it work? and what's the difference between "PST migration wizard" and "Locate and Migrate" c I tried the manual import it's working for the big PST?
I have heard of projects succeeding but as a person who worked for a company selling a solution competing with the native functionality I can tell you there are several projects I know of who have kicked off enterprise scale migrations with this native functionality and it falls apart for a number of reasons at scale. Large PST files is one of them. I am not saying it is not possible....but it is not uncommon for people to get deep into this to realize they cannot do what they are seeking with it. Have you investigated your specifics with support?
most of the large PSTs are failing with the same error messages:
what is going wrong here I cannot migrate any PST larger than 5 GB, I have an antivirus agent running but the firewall is stopped, any idea how to make it work?
I think you will need to DTrace or BackTrace the issue to really get more details. That is a generic windows error message that has a history of mis-representing issues in EV. the assocaited hex can be meaningful, and frequently it implies access is denied or expected access unavailable or lost IMHO.
the issue is happening even for small PST, always getting the same errors during the copy/migration phase:
could not copy pst file the specified network is no longer available
Migration of PST xxx, exception: could not copy PST from PST holding folder to PST migrator task's temporary file folder, the specified network is no longer available
Anyone faced those issues before using server-side migration "Locate and Migrate" and how to overcome c it's affecting a huge amount of PST files?
