RTC ugrade/migration


Gregor Berlisk (111) | asked Jan 26 '17, 7:04 a.m.

  Hi,


Is it possible to migrate/upgrade RTC v4.0.6 to v6 and move to the new hardware at the same time?
We also have to upgrade IBM Websphere application (now v 7.0.0.31) server and IBM DB2 database (now v9.7).

Kind Regards

Gregor

Hi,

4 to 6 isn't possible afaik, you'll have to go 4 -> 5 -> 6.
In general I would avoid to many steps in one "migration" to get the risk and complexity as low as possible.

I would go the following way:
Upgrade to 5 on the old hardware
Switch to new hardware, where WAS 8.5 with RTC 5 is installed
Upgrade to 6 in the new environment

DB2 upgrade whenever possible or needed

If you're using Data Warehouse at the moment, you'll have to switch to Data Collection Component to get to 6.

If you are using SCM, one of the 5.0.x upgrades introduced version numbers, which are calculated in the upgrade process. In our environment this took around two hours. Should be depending on the amount of files and versions.

greetings georg.

 Hi Georg,


Thank you for your quick answer.
Can you be more specific, what do you mean by switch to new hardware. How to switch to new HW?

Kind regards

Gregor

Assuming you are using a DNS alias, pointing to your old hardware:

- install the applications on the new hardware, RTC in the same version as on the old server
- shutdown the services on the old hardware
- switch the DNS alias to the new hardware
- run server.net/jts/setup to configure the new system to use the existing databases and to doublecheck other settings

 Also make yourself familiar with backup: https://jazz.net/wiki/bin/view/Deployment/BackupCLM because it explains the files you need to know if you want to change to another machine.

Great!

I hope I'm not too demanding but I have one more question.

Database DB2 is on same server as RTC (same HW).
Also we would like to have RTC and DB2 together on the same new HW.
Do you think that the next steps are possible:
- install DB2 on the new server (HW) in the same version as on the old server
- install the applications on the new hardware, RTC in the same version as on the old server
- configure new RTC to use databases on new server (same server)
- shutdown the services on the old hardware 
- backap databases on old server
- restore databases on new server
- switch the DNS alias to the new hardware

Kind regards

Gregor

 You want to really read up on the Deployment Wiki. For example, you want to understand the recommended Standard Topologies https://jazz.net/wiki/bin/view/Deployment/StandardTopologiesOverview and how to distribute the applications if you want to go to 6.0.x. Even if you only have RTC, you want to consider the changes to reporting. (RB/DCC)  


Usually the suggestion is not tho have the DB on the same server. How to move the DB to another server is something to look up in the Online Documentation of the DB. What matters for CLM/RTC is the database connection properties still work.

In general, it is a good idea to ask for general advice here, however, you still want to read the interactive upgrade guide and test the upgrade and not rely on the information here alone.
