How to Upgrade from ArcSight 4.5 to 6
I would like to know how to upgrade form ArcSight 4.5 to 6. What are the possible options.
What is the procedure.
Kindly share any Docuemtns, Case Studies, Artifacts etc.
Your help is greatly appreciated.
Thanks & Regards
currently there is no supported upgrade from ESM5 to ESM6, so you probably can save yourself the trouble of upgrading from 4.5 to a current 5.2 or 5.5 install (which would include a lot of steps).
For now, no event data can be carried over from 5.x to 6 and the official answer is to get professional services in to migrate content. I have had some success migrating content with the archive tool.
So for us, the planned procedure would be to:
- reinstall one of two ESM instances with ESM6
- recreate data feeds
- migrate custom content
- let old and new system run in parallel for the retention time and verify that content works the same
- train & switch operations to use new system
- decommission old system or reinstall with 6.0
Actually your method is the official recommended procedure. PS would probably also not help to move events. The recommendation for PS is for custom content migration. While you can do it using export and import, PS has a content migration tool that would simplify and shorten this process.
