hi @madonnaIb,
For replacing components across 2000 pages in AEM, automation is strongly recommended over manual updates. Manual replacement would be extremely time-consuming, error-prone, and inefficient at this scale.
Here is a list of recommended automated Approaches:
1) Groovy Console Script
The AEM Groovy Console is the most popular solution for bulk component replacement. This approach allows you to write a script that finds and replaces component resource types across all pages programmatically. A basic Groovy script structure would query for nodes with the old component's sling:resourceType and update them to the new component path.
2) ACS AEM Tools
ACS AEM Tools - Resource Type/Template Update provides built-in utilities for bulk updates, including tools specifically designed for updating sling:resourceType or cq:Template properties across multiple pages. This is a more user-friendly option if you prefer not to write custom scripts.
3) Apache Sling Pipes
Sling Pipes offer a declarative approach to content transformation and are well-suited for complex migration scenarios where you need to find, filter, and modify content in a structured way.
Before executing any bulk replacement, create a complete backup of your AEM repository to safeguard against data loss. Test your script thoroughly in a staging environment first to identify and resolve issues before running in production. Run your migration during off-hours to minimize impact on content authors. After migration, verify data integrity and conduct thorough testing to ensure components render correctly.
Besides, consider processing content in batches rather than all at once to avoid overloading the system.
