Migrating the Software

A migration needs to be planned very well. Read carefully everything and schedule it for a time when there is no working shift or when there is less to do. Schedule sufficient time for the change over. If you have the facilities, setup the new PC in a protected network range where one of the machines is available and you can test the change over.

  1. You want to migrate the PPS installation to another, for example more powerful PC.
    1
    First of all, install the same state of the PPS software including all updates of this state on the PC.
    2
    Copy all files you have changed or added and that you will need again from the D:\PPS directory and the subdirectories to the new installation.
    3
    If you have carried out modifications on the D:\PPS\PpsJBossServer\standalone\configuration\ standalone-full.xml and/or on the server.keystore, please, copy them as well.
    4
    Copy your private files under C:\Program Files (x86)\Apache Group\Apache2\htdocs\PpsDocs\CustomerWeb or added or changed files under C:\Program Files (x86)\Apache Group\Apache2\conf to the new target directory of the SNS.
    5
    Generate a backup of the SNS database and load it into the installation of the SNS. (Backup)
    6
    In case it is not available, generate a backup of the PostgreSQL database.

    7
    Disable the Skr3_DB(_15) service in the service manager of the former productive system.
    This ensures that later on there will not be two PCs trying to access the machines and obstruct each other.
    8
    Load this backup into the new installation.

    11
    Setup the permissions and directory shares for your users in the same way as before.
    12
    If you use the automatic backup of the PostgreSQ database, set it up as in the other PC.

    In case you use antivirus software, take into account these notes: Security
  1. The preparatory work are finished now and the new installation can be tested.
  1. Now, you can disconnect the old computer from the network and use it for other purposes. It is recommended to maintain the SKR3_DB(_15) service deactivated and not to uninstall the PPS- software until you have used the new PC during an acceptable time period and are sure that you transferred all the files needed. For security purposes you can generate an image backup before uninstalling.
