Hey,
The Best way would be:
Apply the patch on the secondry one first and then on the primary box.
You dont really need to make any box a stand alone one. You can apply the patch in the ditributed enviorment.
One more thing:
If you apply the patch on the primary box and then perform replication.It WILLNOT replicate the patch on the secondry box.
Here is the procedure:
Steps to apply the patch
Issue the following "acs patch" command in the EXEC mode to install the ACS patch:
"acs patch install patch-name.tar.gpg repository repository-name"
ACS displays the following confirmation message:
Installing an ACS patch requires a restart of ACS services.
Would you like to continue? yes/no
Enter yes.
Please ensure that you use FTP server. Donot use TFTP as its not supported.
