Hello! I was trying to update my splunk version from 7.2.1 to 8.1.4, I made all the steps required here: https://docs.splunk.com/Documentation/Splunk/8.1.2/Installation/AboutupgradingREADTHISFIRST?utm_medium=email&utm_source=splunk&utm_campaign=FY22Q1_GLBL_RTN_CUS_PLT_EN_7273EOS_Em2Apr21 and Here https://docs.splunk.com/Documentation/Splunk/8.1.2/Installation/UpgradeonWindows But after run the Upgrade Splunk Enterprise using the GUI installer my Splunk is broken. In the splunk.log file there is the following: Finished generating checksums for datamodel and report acceleration bucket summaries for all indexes. [App Key Value Store migration] Checking if migration is needed. Upgrade type 1. This can take up to 600seconds. WARN: [App Key Value Store migration] Service(36) terminated before the service availability check could complete. Exit code 14, waited for 2 seconds. App Key Value Store migration failed, check the migration log for details. After you have addressed the cause of the service failure, run the migration again, otherwise App Key Value Store won’t function. [App Key Value Store migration] Checking if migration is needed. Upgrade type 2. This can take up to 600seconds. WARN: [App Key Value Store migration] Service(36) terminated before the service availability check could complete. Exit code 14, waited for 0 seconds. App Key Value Store migration failed, check the migration log for details. After you have addressed the cause of the service failure, run the migration again, otherwise App Key Value Store won’t function. [DFS] Performing migration. [DFS] Finished migration. But I review the migration.log and there are not more information: Generating checksums for datamodel and report acceleration bucket summaries for all indexes. If you have defined many indexes and summaries, summary checksum generation may take a long time. Processed 3 out of 36 configured indexes. Processed 6 out of 36 configured indexes.
