    I am using WHM on the new server to transfer all accounts from my old server.

    1. I am getting the following warnings:

    TRANSFER: Account “djbaxter”: Unable to remove archive from remote system for user “djbaxter”.
    RESTORE: Account “djbaxter”: Unable to remove archive from remote system for user “djbaxter”.
    TRANSFER: Account “daniel”: Unable to remove archive from remote system for user “daniel”.
    RESTORE: Account “daniel”: Unable to remove archive from remote system for user “daniel”.

    Not sure what that means. Can I safely disregard it?

    2. I am getting the following errors:

    RESTORE: Account “littlegulllake”: Warnings
    The MySQL restore process died from the “SEGV” signal.
    The MySQL restore process died from the “SEGV” signal.
    The MySQL restore process died from the “SEGV” signal.
    The MySQL restore process died from the “SEGV” signal.
    RESTORE: Account “runningw”: Warnings
    The MySQL restore process died from the “SEGV” signal.
    RESTORE: Account “drdavidb”: Warnings
    The MySQL restore process died from the “SEGV” signal.
    RESTORE: Account “somasem”: Warnings
    The MySQL restore process died from the “SEGV” signal.
    The MySQL restore process died from the “SEGV” signal.
    RESTORE: Account “tsfc”: Warnings
    The MySQL restore process died from the “SEGV” signal.

    Again, I don't know what that means. The databases appear to have traneferred to the new server but does that mean I need to import them manually?

    Hello,

    Internal case CPANEL-11297 is open to address reports of this error message during the transfer process. This seems to be a non-fatal error message based on reports we have received thus far (e.g. the databases should have been successfully restored), but would you mind opening a support ticket using the link in my signature and referencing case CPANEL-11297 so we can take a closer look at the affected system? You can post the ticket number here.

    Thank you.

    I did open a priority support ticket with cPanel. At the time, I was having email issues so I no longer have the ticket number but I received a response to the ticket and was assured that I could safely ignore the warnings and errors. The account transfers did complete successfully and all my sites are now live on the new server.

    Thank you for the response.

    I'm having the same error when trying to migrate. Almost half of the migrated accounts have reported "The MySQL restore process died from the “SEGV” signal". Opened a ticket as well (#8343381).

    Are you 100% sure that I can continue with the migration? I really need to do it tonight as I already notified all our customers... :|

    Hello,

    Internal case CPANEL-11297 should address the issue, but it's not yet been published to cPanel version 62. However, it has been published to cPanel version 64:

    Fixed case CPANEL-11297: Update B::C to version 5.024009-4.cp1162.

    cPanel 64 is currently available in the "Current" and "Edge" build tiers. You can review more information about the build tiers and the release process at:

    Product Versions and the Release Process - cPanel Knowledge Base - cPanel Documentation

    Thank you.

    Yes, it's normal. Happens after each DB transfer completed. If some DB transfer fails you'll see the error message.

    Still experiencing this,
    source and destination servers are on 68.0.20

    Code:
    ERROR: mux_client_request_session: read from master failed: Broken pipe
    ERROR: ssh: Could not resolve hostname child: Name or service not known
    ERROR: Use of uninitialized value $s in split at /usr/local/cpanel/Cpanel/Expect/Shell.pm line 245.
    ERROR: sshcontrol execution encountered a fatal error: (XID jz3d5e) Critical SSH or support files appear to be missing: Failed to normalize shell: (XID na8z8b) The system failed to detect the remote shell. This probably indicates misconfiguration on the remote host or very high system load.
    Only happens for some of the transferred accounts. BTW this forum does not let me edit my posts

    That's correct. New user are not permitted to edit. In time as you become more active, options like editing posts and profile should open up for you.
