documentum xplore

Hi, there, I have some question about documentum and xplore.

I move documentum from old machine t onew machine and using a new install owner. (old install owner: Administrator, new install owner:test01)

But when I install xplore and use the new install owner test01 to install index agent, error shows:

[DM_SYSOBJEcT_E_INVALID_ACL_DOMAIN] error: "The dm_ftwatermark 'Reindex 07/21/17' is given an invalid ACL domain 'Administrator'.",; ERRORCODE:100; NEXT:null. I can only using old install owner 'Administrator' to install and reindexing.

Another issue is I successfully installed xplore index agent, and after indexing, "Start Index Agent in Normal Mode", but when I add new folder or new file, it seems can not auto send to indexing server, I don't know why.

Could anyone help, thanks in advance.
