About this document

The purpose of this document is to give a brief overview of the migration process which allows SNA profiles to be converted from the format used by SNA Services/6000 V1.2, SNA Server/6000 V2, SNA Server/6000 V3, and Communications Server Version 4 for AIX to the format used by Communications Server Versions 5 and 6 for AIX. This document is one in a series of documents that aid in Communications Server Versions 5 and 6 configuration. This document applies to AIX Versions 4.x.

Exporting SNA Services or Communications Server profiles

Before upgrading the AIX operating system, and before installing Communications Server V5 or V6, complete the following steps.

  1. Install the latest PTFs for the version of SNA in use.
  2. Export the SNA Services or Communications Server profiles by issuing the command:
  3.          exportsna [-C] -f [filename] [-S SecurityFile]
    filename specifies the output file that will contain all of the exported SNA Services profiles.

    The -C switch instructs the exportsna command to export from the committed configuration database. This is not an option on some earlier versions of the SNA software.

    The option for the security file is only needed if security is being used.

  4. Place this file in a file system other than /var or /etc so that it will not be overwritten during the installation of Communications Server Version 5 or 6. For example, place this file in /tmp or a user home directory. Preferably, save this file to external media, such as diskette or tape. In the unlikely event that a migration problem arises, it will be essential to have this file readily available.

Install Communications Server V5 or V6 for AIX

Upgrade the AIX Operating System to AIX Version 4.1.5 or a later version. The next step is to install Communications Server Version 5 or 6. Before installing the base level media (5.0.0.0, 5.0.2.0, 5.0.4.0, or 6.0.0.0), first check the Communications Server for AIX support page
( http://www.ibm.com/software/network/commserver/support/fixes/csaix.html) for any available recommended maintenance updates (PTFs) that might supersede the level on hand. Since the introduction of the product, there have been numerous updates and enhancements which minimize the impact on some legacy environments brought about by this version's strict adherence to the SNA/APPN architecture. It is advised to have available and installed, the current recommended maintenance level before proceeding with the migration from an earlier version. After installing the base media and any applicable PTFs, proceed with the migration by converting the old profiles according to the following guidelines.


Using migration tools to convert old profiles to V5/V6 format

The overall migration process has two parts: converting the version 1.2 profiles to version 4.2 format, and then converting the version 4.2 format to version 5/6 format.

NOTE: Profiles from v2, v3 and v4 all share the same format.

Converting the version 1.2 profiles to version 4.2 format

NOTE: This step is only necessary if you are migrating from SNA Services/6000 v1.2. If you are migrating from SNA Server/6000 v2, v3 or IBM Communications Server Version 4.2, please skip this step.

Migrate the SNA Services Version 1.2 profiles to Communications Server V4.2 format with the following command:

         migratesna -s [sourcefile] [-t <targetfile>] [-l <network.cpname>]

Parameters:

Converting the version 4.2 format to version 5 or version 6 format

Migrate the version 4.2 profiles to version 5 or version 6 format with the following command:

         snamig -o -f OldTextConfigFile [-S OldSecurityFile]
OldTextConfigFile is the same file name as
targetfile from the preceding section of this document.

The -S option, for security definitions, should only be used if security is being used and a security file was exported prior to upgrading SNA. If this is the case, the OldSecurityFile is the same file as SecurityFile from the preceding section.

The default settings for the optional flags of this command create the following file names for the converted profiles:

         /etc/sna/sna_node.cfg
         /etc/sna/sna_domn.cfg
         /etc/sna/sna_tps

Starting Communications Server V5 and V6 for AIX

To start the Communications Server, complete the following steps:
  1. Start the SNA daemon with the command sna start.
  2. Start the SNA node with the command snaadmin init_node.
  3. To use the preferred method of controlling and administering Communications Server Version 5 and 6 for AIX, start the graphical interface tool with the command xsnaadmin. If a graphics interface is not available, SNA resources may be started manually from the command line or by using SMIT.

Please refer to the Quick Beginnings Guide (GC31-8583) for further information on starting and using Communications Server for AIX Version 5 and 6.
