Inplace migration of Integration node form ACE11 to ACE12

Hi Team, We are planning to migrate our Integration nodes which are running with to ACE 12.0.3, as per the instructions we have on IBM it seems we need to add the -- delete integration node when we run the extractcomponent command. In case if we need to do roll back we need to run restorebroker and we may encounter some issues either the binary files or config file might be corrupted which leads issues on Runtime. To avoid this kind of scenarios we would like to have an inplace migration from V11 to V12 which can be migrate the nodes and can remove the older version of Node. Please review this request and do the needful

    RFE Review. Thank you for taking the time to submit this idea for enhancement. Due to ACEv11 introducing the new option of running independent integration servers (which should be used when running ACE as part of a container based architecture), we decided to rebrand our migration command so that it could be used to assist all migration situations - including those which involved in-place migration of an integration node, and also those involving a period of parallel execution of an old and a new integration node, and also those involving splitting apart a set of node-owned integration servers as separate independent integration servers. The mqsiextractcomponents command is helpful for all these scenarios. If you are intending on running the integration node on the same machine before and after the migration, and have the integration node take the same name both before and after the migration (ie what is often referred to as "in place" migration) then you can use the mqsiextractcomponents command to achieve this with the "--delete-existing-node" option. This option deletes an existing node before creating the new node by writing the extracted configuration and resources. This option is required if "--target-integration-node" names an integration node that already exists. In this situation, if you were to want to revert back and "undo" the migration for any reason, then you should do so using the back-up file which you will generate using the mqsibackupbroker command prior to executing the mqsiextractcomponents command. You can restore from this backup. Examples of the commands to execute are as follows:

    IIBv10: mqsistop YourExistingIntegrationNodeName

    IIBv10: mqsibackupbroker YourExistingIntegrationNodeName -d C:\temp

    ACEv12: mqsiextractcomponents --backup-file "C:\temp\" --source-integration-node YourExistingIntegrationNodeName --target-integration-node YourExistingIntegrationNodeName_043390866 --delete-existing-node

    ACEv12: mqsistart YourExistingIntegrationNodeName

    To delete the migrated node and revert back the migration ...

    ACEv12: mqsistop YourExistingIntegrationNodeName

    IIBv10: mqsirestorebroker YourExistingIntegrationNodeName -d "C:\temp" -a

    IIBv10: mqsistart YourExistingIntegrationNodeName

    This is exactly the same capability as previously offered through mqsimigratecomponents.
