When you upgrade ESM Manager to CCS Manager, the new .m files overwrite the existing .m files on the CCS Manager. The overwrite may result in loss of the customized files. You can preserve the .m files on the manager by changing the customized value of the modified messages to a 1 in the .m files.
You must relaunch the ESM console to view the changes that you made in the .m file.
Perform the indicated steps to preserve the customized .m files on the ESM manager.
To preserve the customized .m files
Open the .m file from the following location:
<Installdir>\CCS\Reporting and Analytics\ESM\content\su\<platform>\register
Set the customized flag as 1 after you make the required changes in the message.
Run the importcontent utility to import the .m files using the -a option.
