Upgrading to i2 Analyze version 4.3.1
When you upgrade your deployment to i2 Analyze version 4.3.1, Solr is also upgraded to version 8. Any search indexes created in Solr 6 are not compatible with Solr 8. As part of the upgrade process, you must recreate the index.
There are two approaches that you can use to
perform the upgrade:
- Offline reindex
- If your system can be taken offline while the
upgrade is completed, you can stop your system,
upgrade your deployment, and reindex the data in
your Information Store. The time that it takes to
complete the reindex of your data depends on the
quantity of data. While the data is being indexed,
the system is unavailable to analysts.
To complete the offline reindex, follow the instructions in Upgrading to i2 Analyze 4.3.1 offline.
- Online reindex
- If your system must be available for use while
the reindex is completing, you can create a second
system alongside your current system, and use that
system to create an index of your data from a copy
of your Information Store database. After the
indexing process is complete, you can update your
production system to use the new index. In this
approach, your production system is down for a
short time to complete the upgrade of the
application, but it is still available to analysts
while the index is created.
To complete the online reindex, follow the instructions in Upgrading to i2 Analyze 4.3.1 online.
