Sorry for the small book here, but maybe all this will help.
Only one v7.1 NS, and 6 site servers with task server and package server services. One of the site servers is here at the home office to take the load off the NS. The other 5 are at some of our remote locations.
We have two v6 NSs that we migrated from and consolidated into one v7.1 NS. We have a v6 Client Management Suite server that computers reported in to, and it forwarded inventory over to the v6 Service and Asset Management Suite server. The two v6 NSs are still in place because we have a few remaining PCs that are reporting in to the CMS server that have to be moved over to the new v7.1 NS. And, the v6 SAMS server is still running because we still use the HelpDesk. As soon as I get this issue resolved, we'll move on to installing and migrating to ServiceDesk v7.1.
The migration process went something like this:
- I disabled all of the agent installation policies and enabled all the uninstall policies - for everything except the NS Agent.
- I created a new "migration" collection to use to migrate computers.
- Other collections were added to the migration collection when it was their turn to migrate.
- This "migration" collection was excluded from the normal NS Agent settings policy.
- A new NS Agent settings policy was created to apply to this migration collection and was changed to add the alternate URL in the advanced settings, just like the documentation said to do. I did this by location as well, because the package servers had to be done at the same time for each location.
- I exported the v6 NS data, and then imported them into the v7 NS, using the data migration tool supplied by Symantec. There's a lot of "stuff" that gets exported, so maybe I exported/imported something I shouldn't have. The documentation wasn't very clear on what to export/import.
- Once v6 data was imported and a random check of asset associations verified for Asset Management, a small pilot group of about 20 PCs was migrated.
- Migrated PCs were checked for agent upgrades and the new additional agents.
- Again, asset associations were checked in Asset Management.
- Once the information was verified, the migration colletion/policy was enabled on the v6 NS. Another 50+/- PCs were migrated.
- Agent upgrades checked and asset associations checked.
- We waited a couple of weeks to ensure everything was working properly and then began the full migration of about 300 PCs per week.
The 'New Computers' and 'Installed Agents' filters were worthless for a migration, so I created a new one to see which agents had migrated and upgraded their agents. As PCs were reporting in to the new v7.1 NS, and agents upgraded, they were deleted off the v6 CMS, but left on the v6 SAMS (mostly for historical purposes, and for reporting until all were on the new NS).
Once 'all computers' had been migrated, cleanup began for those that were remaining on the v6 CMS. It turns out that some agents had migrated to the new server, but didn't upgrade, so my filter missed them. Those PCs were removed from the v6 CMS. We still have agent upgrade cleanup to do, but we have tracked down all but a few remaining PCs on the v6 CMS that just won't migrate. But that's a different problem.
Everything seemed to be running fine for about two weeks, and then I got the email from the server administrator. The C: drive was full. That's when I found out that the server wasn't processing NSEs, and had filled up the C: drive. I backed off the agent inventory policies and configuration requests. I also backed off the amount of data agents report - events, application stops/starts, etc. This was all the normal information we collected with our v6 CMS server. The next day the C: drive was filling up again. NSEs were being received for policies that were not set - to my knowledge anyway. I went through every policy and setting that I could find to see if any changes could be made to reduce the amount of NSEs, but didn't find anything.
I started looking at the NSEs to see what policies/settings were being reported. Turns out it is everything - all inventory, application stop/starts, events, client logons, etc. I checked the client policy XML of one of the computers that was continually uploading NSEs, and that's when I saw the v6 SAMS server is listed in a v7.1 collection. I checked my computer, and it is listed there as well. Agents never reported to that server, so I don't know why that one would be listed in a new v7.1 collection.
I've been going through some of the NSEs in the 'bad' folders, and some are empty - 2kb and empty. Some agents are reporting the same inventory/events every 30 minutes.
I used DS to run NSAgentUtil.exe to remove all servers and then set the server to the new v7.1 server and that didn't help.
I deleted all NSIs and BAK files from two computers, and after checking in with the server, they started reporting inventory/events again.
Right now my best guess is that something went wrong with the import of data, or I imported something that I shouldn't have imported. Another guess is that the agent upgrade didn't go well and I might have to wipe all agents off every computer, and then re-install. One option would be to re-install the NS and start over from scratch, only importing computers. We'd have to go through and re-associate computers to owners again, but that may be the only way. Historical data would be lost as well.
