I'm trying to update a SUSE 11 SP3 to SP4 and I'm having a block due to an extension not being available in SP4. For some strange reason, only the newest VMs I had created have this issue.

When I do a zypper migration, I get the following:
Unavailable migrations (product is not mirrored):

        SUSE Linux Enterprise Server 12 SP4 x86_64
        SUSE Linux Enterprise Software Development Kit 12 SP4 x86_64
        SUSE Package Hub 12 SP4 x86_64 (not available)
        Web and Scripting Module 12 x86_64 (already installed)
        Toolchain Module 12 x86_64 (already installed)
        Containers Module 12 x86_64 (already installed)
        Public Cloud Module 12 x86_64 (already installed)
        Advanced Systems Management Module 12 x86_64 (already installed)
        Legacy Module 12 x86_64 (already installed)
Here's the output of SUSEConnect:
command 'zypper --non-interactive removeservice 'SMT-http_smt-ec2_susecloud_net'' failed
Error: zypper returned (1) with 'Unexpected exception.
[SMT-http_smt-ec2_susecloud_net|file:/usr/lib/zypp/plugins/services/SMT-http_smt-ec2_susecloud_net] Can't figure out where the service is stored.
Please file a bug report about this.
See http://en.opensuse.org/Zypper/Troubleshooting for instructions.'
It seems the SUSE Package Hub 12 SP3 x86_64 (Installed) extension is blocking the migration path as it's not available in SP4, but I'm unable to remove it...
# SUSEConnect -d -p PackageHub/12.3/x86_64
Error: Registration server returned 'Single product deactivation is not available when registration sharing is enabled' (422)
If I try to enable the product extension in SUSEConnect, I get the following:
# SUSEConnect -p PackageHub/12.4/x86_64
Error: Registration server returned 'Product not (fully) mirrored on this server.
Mirroring of the following repos has to be enabled on the SMT server:
 * SUSE-PackageHub-12-SP4-Pool (PackageHub,12.4,x86_64)
  * SUSE-PackageHub-12-SP4-Standard-Pool (PackageHub,12.4,x86_64)
' (422)
Thanks for your help
