Upgrade Path for DCE 7.2.5 to 7.2.7

[DCIM_Support]

We decided to migrate the physical DCE version 7.2.5 to a virtual DCE version 7.2.7. The virtual DCE is up and running, and we have applied the new license key. However, when we tried to restore to 7.2.7 the backup done in 7.2.5, we could not see any of the backup files. Reading the forum, someone mentioned that we can only restore a backup performed in the same DCE version.

Question:

1. do we have to upgrade the physical DCE from 7.2.5 to 7.2.6 first, or can we upgrade the physical DCE directly from 7.2.5 to 7.2.7?
2. our 7.2.5 have 1TB disk space, but we only use 300GB currently. furthermore, we intend to only migrate the Configuration without migrating the CCTV footage, does that mean we still need to create a 1TB volume in the virtual DCE? because I read in the migration documentation that the virtual DCE has to match the configuration of the physical DCE (e.g. CPU, RAM, Disk space etc.)

Thanks very much!

Cheers, Simon

Simon,

You will need to upgrade your physical appliance to DCE 7.2.7 first.  Your local technical support shouldbe able to assist with the necessary upgrade links.  A backup can then be created and brought into you virtual DCE appliance.  The disk space just has to be greater than the amount being used by your physical DCE server.

"The available disk space for the virtual appliance must
be greater than the disk space used by the hardware server."

Best Regards,

Dear Simon,

Please find my responses to your query.

1. do we have to upgrade the physical DCE from 7.2.5 to 7.2.6 first, or can we upgrade the physical DCE directly from 7.2.5 to 7.2.7?
   1. Yes, DCE version 7.2.5 has to be upgraded to version 7.2.6 before upgrading it to 7.2.7. You are correct that restore of the DCE backup can be performed in the same DCE version.
      
      
2. our 7.2.5 have 1TB disk space, but we only use 300GB currently. furthermore, we intend to only migrate the Configuration without migrating the CCTV footage, does that mean we still need to create a 1TB volume in the virtual DCE? because I read in the migration documentation that the virtual DCE has to match the configuration of the physical DCE (e.g. CPU, RAM, Disk space etc.)
   1. In my opinion, Storage space of the virtual appliance can be increased by the user based on the requirement. It does not require 1 TB disk space need to be allocated during the installation itself. It is correct that VM specs has to match with the configuration of the Physical DCE. From the Manual: 
      
      

      Deploy the demo version OVA, and configure it using the hardware equivalents for
      the StruxureWare Data Center Expert Basic, Standard, or Enterprise server from
      which you are migrating. The available disk space for the virtual appliance must
      be greater than the disk space used by the hardware server.

      Hard disk settings: To increase storage for the virtual appliance, you can create additional
      hard disks. You cannot change the size of an existing hard disk, or remove a hard disk once
      it has been created. An error will occur on the primary interface, and the StruxureWare
      Data Center Expert virtual appliance will not start.
      Changes in the disk space will take effect once the StruxureWare Data Center Expert virtual
      appliance has restarted.
      The "Storage Settings" display, accessed from the Server Administration Settings option
      in the System menu, shows the total storage space available for the virtual appliance, not
      the individual hard disks.
      Note: To store large amounts of surveillance data, using a remote repository is
      recommended.

   2. Adding disk space to a virtual appliance
      To increase storage for the virtual appliance, you must create additional hard disks.
      You cannot change the size of an existing hard disk, or remove a hard disk once it has been
      created. An error will occur on the primary interface, and the StruxureWare Data Center
      Expert virtual appliance will not start.
      1. Gracefully shut down the virtual appliance.
      2. In your virtual server console, select the option to add a hard disk.
      3. Choose the hard disk size.
      See StruxureWare Data Center Expert virtual server equivalent configurations.
      4. Choose thin or thick provisioning.
      5. Power on the virtual appliance. StruxureWare Data Center Expert Changes in the disk space will take effect once the StruxureWare Data Center Expert virtual appliance has restarted. 

      Do not shut down the virtual appliance while the disk reconfiguration process is running.
      The "Storage Settings" display, accessed from the Server Administration Settings option
      in the System menu, shows the total storage space available for the virtual appliance, not
      the individual hard disks.

      
      Note: To store large amounts of surveillance data, using a remote repository is
      recommended.

   I hope this helps. 
   
   Regards,
   Bala
