Hi. Now I'm using signoz 0.45 version and trying to upgrade into 0.80 version. I have to migrate old data from signoz_logs.logs into signoz_logs.logs_v2. But it's not easy to do because two tables are so different. Are there any solutions migrate clickhouse data from 0.45 to 0.80?

Hey @최현진, I'll recommend that you identify the upgrade path with our tool: https://signoz.io/upgrade-path/, which can guide you through the upgrade instructions, as there are breaking changes and mandatory upgrades from 0.45 to 0.80.

@최현진 In short, it will involve upgrading slowly to several key milestone releases, making config changes, and migrating data (either by automatic migrations or manually running migrations or adjusting some dashboards and alerts). Depending on how much data you have, it could take a while to complete, and there is a risk of migrations not working correctly. In some cases, it may be easier to spin up a new Signoz instance and redirect telemetry data to it, archiving the old one.

@Nagesh Bansal @Kieran Pilkington Thank you for kind guide. We have 3.5 TB data so it's not easy to migrate old data into new version. Spin up a new Signoz instance and redirect telemetry data to it, archiving the old one looks best way. :)
