Final answer:
Performing a searchable rolling upgrade involves preparing backups, dividing the system to upgrade in segments, upgrading them individually while maintaining search functionality, testing each upgraded part, and finally monitoring the entire system post-upgrade for stability and performance.
Step-by-step explanation:
Steps to Perform a Searchable Rolling Upgrade To perform a searchable rolling upgrade, certain steps need to be followed to ensure that upgrades are applied smoothly and without service interruption. A searchable rolling upgrade typically refers to the process of upgrading an application or a system, such as a search engine or a database, while keeping it available for search operations. Here are the general steps:
- Prepare the environment by ensuring that everything is properly backed up.
- Divide the system into segments or partitions that can be upgraded individually. This will allow for minimal impact on availability.
- Gradually upgrade each segment, one at a time, while redirecting search queries to the other, non-upgraded segments to maintain searchability.
- After upgrading a segment, perform thorough testing to ensure its proper functionality before proceeding with next segments.
- Repeat the process for each segment until all parts of the system have been upgraded.
- Once all the upgrades are complete, conduct a final testing phase to ensure all components are functioning as expected together.
- Monitor the system closely post-upgrade to ensure stability and to quickly address any issues that may arise.
During this process, it is critical to maintain system integrity and ensure that the content loaded and new features are working as intended.
