After installing the Integration FTP (IG FTP) agent to upgrade/replace the RA FTP agent, there is an error message displayed when viewing the agent:
IGFtpSheetProvider
This can be seen in all other FTP objects as well.
Automic Automation v21 with RA FTP and Integration FTP agents
There is a conflict with the sheets between the RA FTP and Integration FTP agents.
In client 0 search for UC_ECC_PLUGINS.
The ecc sheets for both the RA FTP and the IG FTP agents will be listed.
Highlight the sheets for RA FTP and click on Remove, then save the change.
Log out and log in again to client 0 and double-click on the IG FTP agent to open it and the error will now be gone.
