# Upgrading a Logger

Remote upgrades to Logger 7 require a previous hot-fix to be applied if Logger’s versions are any of the following:

• 6.7.0.8242

• 6.7.1.8253

• 6.7.1.8257

• 6.7.1.8262

The hot fix file to be uploaded is preupgrade-logger-20190924.enc. The name should be kept as is.

To upload the file from the master ArcMC:

1. Download the hotfix file and store it in a secure network location. The file name should always be preupgrade-logger-20190924.enc depending on the form factor.
2. Click Administration > Repositories.
3. Select Upgrade Files from the navigation tree.
4. In the management panel, click Upload.
5. Click Choose File and browse to your hot fix file, then click Submit. The file is now uploaded.
6. Continue with the normal procedure outlined in the To remotely upgrade one or more managed Loggers:

In ArcMC, you can remotely upgrade any of the following managed Logger types.

Form Factor | Upgrade File Name | Can Upgrade From Version... | Can Upgrade To Version... | Comments
--- | --- | --- | --- | ---
Appliance | logger-<build number>.enc | 6.0 or later | 6.1 or later | The filename format for the remote upgrade file for Logger Appliance is logger-<build number>.enc
Software | logger-sw-<build number>-remote.enc | 6.0 or later | 6.1 or later | The filename format for the remote upgrade file for software Logger is logger-sw-<build number>-remote.enc Remote operating system upgrade is not supported for software Logger, and, if required, must be performed manually.

Note: Upgrading to Logger version 6.0 requires ArcMC Agent 1167.1 or later to be running on the managed Logger. Upgrade the Agent on the managed Logger before performing the upgrade to Logger 6.0.

To upload the upgrade file to your repository:

1. Download the Logger upgrade file for the upgrade version, as outlined in the table above, and store it in a secure network location.

2. Click Administration > Repositories.

3. In the navigation tree, pick Upgrade Files.

4. In the management panel, click Upload.

5. Click Choose File and browse to your upgrade file, then click Submit. The file is uploaded.
