If your old server had d:\proficy historian data, your new server should be d:\proficy historian data. And we assume you would already have that drive created with enough disk space for your existing archives to be copied there twice. This allows to have (1) a folder that will only be used as a repository for the old archives and never to be read or written to and (2) a backup folder that the existing archives (which will be upgraded) and any new archives will be stored.
Make a note of the paths of every datastore. The .ihc file expects the datastores to be in the same directory that they were in on the original machine.
Notes on copying files:
Get a catalog of the current archives on the old system. You can use excel addin or ihSQL.exe. For ihSQL.exe, you can use the following select statement and copy/paste into notepad and bring it into excel and transform “text to columns”
Code Block select * from iharchives
You cannot copy the .IHC and .IHA files from the source computer while the data archiver is running. If you can afford some downtime (the collectors will buffer) you could stop the data archiver service and start copying. To save time, only copy the files in the catalog from the ihArchives table. The others can be placed in a backup folder because they are not online archives.
If you cannot afford downtime, you can use the ihArchiveBackup.exe to back up everything. The first thing you want to do is to make sure your backup directory has been set to a different folder than the archives folder.
