# Post-Migration Procedures

This guide provides instructions on what to do after a successful software migration. Follow the sequence of procedures to apply the updates in the Core Client setup.

Verifying Core Client Installation

# Reapplying Core Client Configurations

Follow these steps to migrate from the old Core Client to the new version:

Navigate to the C:\Program Files\OpeniT\Core\Configuration folder in the backup client directory. Identify and review all customizations made to the configuration files in this folder.

Customizations may vary based on the customer's specific setup.
Apply the customizations found in the old client configuration files to the corresponding files in the new client.
Copy the bookmarks of log-based collectors in C:\Program Files\OpeniT\Core\Log\temp from the old client to the new client installation directory.

Bookmarks have the timestamp of the last collection done on the logfiles. Copying the bookmarks will avoid previous logfiles (before the timestamp) to be recollected. Incorrect management of non-Flex-based (flex log) log file collections may cause data doubling.

Navigate to the /var/opt/openit/etc/ folder in the backup client directory. Identify and review all customizations made to the configuration files in this folder.

Customizations may vary based on the customer's specific setup.
Apply the customizations found in the old client configuration files to the corresponding files in the new client.
Copy the bookmarks of log-based collectors in /var/opt/openit/temp from the old client to the new client installation directory.

Bookmarks have the timestamp of the last collection done on the logfiles. Copying the bookmarks will avoid previous logfiles (before the timestamp) to be recollected. Incorrect management of non-Flex-based (flex log) log file collections may cause data doubling.

Navigate to the /usr/local/openit/etc/ folder in the backup client directory. Identify and review all customizations made to the configuration files in this folder.

Customizations may vary based on the customer's specific setup.
Apply the customizations found in the old client configuration files to the corresponding files in the new client.
Copy the bookmarks of log-based collectors located in /usr/local/openit/temp from the old client to the new client installation directory.

Bookmarks have the timestamp of the last collection done on the logfiles. Copying the bookmarks will avoid previous logfiles (before the timestamp) to be recollected. Incorrect management of non-Flex-based (flex log) log file collections may cause data doubling.
