Hi All, 

 

We have the challenge to migrate all the workflow live instances from K2 4.6.11 to K2 4.7.

Here is the situation :

We were using K2 4.6.11 version running with several live apps and now instead of upgrading the same server, a brand new server has been set up with K2 4.7 and all the old version apps are getting upgraded separately on some other dev server and then deployed on the new server. Most of the apps are deployed and has gone live using the new K2 4.7 server.

But there is one app where we faced a lot of issues while upgrading but finally, it is upgraded to K2 4.7 with the package ready to be deployed on the new server (K2 4.7). The challenge is we have thousands of workflow live instances running on the old version which we also need to migrate to the new server.

What we cannot do is to take a backup of K2 database from the old server and restore to the new server and run config to pick up restored K2 database to update the changes as we have apps running on the new server already.

 

Any help is highly appreciated !!

 

Thanks,

Vishal

HI VS

 

Take note of the following before you restore your database to a new server

Hi Elvis, 

 

Thank you so much for your reply.

But I don't think we can use this approach as I have mentioned before we have running applications with live instances on the new server.

What would you suggest to migrate this only application from the old server(4.6.11) to new (4.7) with its live instances?

 

Thanks,

Vishal

Hi VS

 

installing K2 blackpearl 4.7 against a new database is perfectly fine; however please allow the Setup Manager to create the database.

2. Migrating solutions from 4.6.11 to 4.7 is possible and supported and will likely involve the P&D tool:
https://help.k2.com/kb001782

3. However, it is currently NOT possible to migrate any in-progress items. The only way to have these in-progress items is to upgrade the 4.6.11 database that was migrated for e.g SQL 2012 R2 server.

Good day VS,

This operation is not supported. There is no way to move “active process instances/workflow live instances” between environments. The best approach would be to restore the Database from the environment containing the Active instances into a different environment. You can only restore the full database and not specific tables.

 

Kindly feel free to mark as “Accepted solution, kudo and/me too” if you find this information answered your question or leads to your answer.

Thank you and kind regards,

Hi Vs;

 

Unfortunately, it is not possible to move an active instance of a workflow that was started on i.e. version 1 of the workflow to version 2 of the workflow.
Here is an example: suppose that you can deployed V1 of a workflow design, and 10 instances of that workflow start. Each of these instances will continue running on the V1 definition of the workflow for their entire lifetime, even if you deploy V2 of the workflow design. By default, Workflows start on the "Default" version of the workflow and this is usually the last version that was deployed when the workflow starts. While you can use the K2 management tools to declare a different version to be the default version of a workflow, this will not affect active instances of the workflow.

Good day Vishal

 

It is possible and normal to upgrade your K2 with active instances. This process will not affect any of the instances. The move to the new server can then be done by using the documentation explaining to do so. Click here for the document that is also listed below. Choose your relevant scenario and the steps can be followed. Just a small heads up, When moving the database an encryption and decryption process takes place. A script must be run to decrypt the database which can be found in the documentation here. A key is needed for this script but sadly a support ticket must be logged requesting the Key.
