Version Upgrade from ES 4.0 to 6.0

Is there any  step by step procedure document?

Hi, I recommend you to review the relevant readme file (e.g. mfenterpriseserver-60-release-notes.pdf) to understand the steps involved. Regarding backups I suggest creating exports of ES regions/configurations, also backup application data/deployed application modules/sources, so in the unlikely event you need to rollback you are able to do so.

Hi Kim,

We have prepared a checklist for performing upgrade in a temporary server which will be for the upgrade testing activities.

Is the below checklist items is fine? Also for CICS-Online region is there any other items which we have missed out?

Hi,

Unfortunately I do not have visibility into details of your points, such as "Backup existing MFES setup",  therefore it will be difficult for me to confirm your checklist is fine, if you create region exports and backup application related files/sources/projects then I suspect that will suffice, also review the mentioned readme for any further recommendations.

If you need further confirmation, before proceeding with any upgrade plan I recommend you to consider raising a support case to get this confirmed by appropriate colleagues.

Hi Kim,

from fileshare perspective what do you think can be verified? is the filehare utility similar in version 4.0 & 5.0

Hi, I do not expect there to be any changes, it can depend on your configuration. I recommend you to review the readme in case there is something to be aware of. Do you have a special fileshare configuration, or standard? As before I would backup any configuration just in case you find that you need to revert something.  

Hi Kim,

Fileshare is in the same server where MFES is installed. 

Hi Noel, As suggested before, review the readme in case any changes affect your situation, make backups of any configuration, does that help to answer your question?

Hi Kim,

Can we upgrade Enterprise Server from 4.0 to 5.0 without upgrading Enterprise Developer? Is it mandatory that ED & ES should have the same versions

Hi Noel,
It is recommended to use the same version between ED and ES, also I recommend to recompile the affected application modules on the new version and re-deploy those, this will ensure full compatibility, avoid potential unexpected errors.  E.g. you may be lucky not to encounter any problems but say for example you use COBOL programs that make use of an entry point in a product module in 4.0, if that entry point changes (for whatever reason) in the newer 5.0 version then it could cause a problem, this is just one example I can think of, there could be other scenarios.

HI Kim,

In order to rebuild the RM switch module after the ES version upgrade, what steps to be followed?
Also how to get customized source file of the ESODBCXA module?

Hi Noel,

Which module do you intend to build, e.g. the ODBC module, in that case you can read more about how to do this in the product documentation, e.g. see URL: https://www.microfocus.com/documentation/enterprise-developer/ed70/ED-VS2017/GUID-08CB666F-83C7-45D2-AA71-FBDB5D78B95D.html 

For a custom ESODBCXA module, you can locate the source that ships with the product, typically from path C:\\Program Files (x86)\\Micro Focus\\Enterprise Developer\\src\\enterpriseserver\\xa , then modify that as needed, then rebuild the source as instructions in above documentation.
