Rollback Options: Can You Revert to T5.3.18?

Yes, but with caveats. The database schema changed minimally between versions (one new index, no column changes). This means binary compatibility is preserved.

Rollback procedure:

# Stop T5
sudo systemctl stop t5-core
# Reinstall older package
sudo dpkg -i t5-core_5.3.18_amd64.deb   # or rpm -ivh --oldpackage
# Restore configuration from backup
sudo cp /opt/t5-backup/config.yaml /opt/t5/config/
sudo systemctl start t5-core

Warning: Any new data written by T5.3.19 that utilizes the new lazy-loading cache format will be ignored after rollback, potentially causing missing records. Always take a full database dump before upgrading if you anticipate needing a rollback.

Quick troubleshooting pointers

  • If service fails to start: check config syntax and environment variables first.
  • If APIs time out: inspect connection pools, thread counts, and DB metrics.
  • If new errors appear in logs: search release notes for related bugfixes/behavioral changes.
  • If high memory/CPU: consider reverting and running profiler in staging.
