Problem with Omniback 4.1 and Informix

Hello, I am doing some tests to upgrade Omniback, from 3.5 to 4.1 I have two problems: # 1 I can't do an Informix 7.3.1 online backup with a 3.5 client. It says that the version is not the same. I want to upgrade the cell server first and do the clients not at the same time. I know that the database should be down when we upgrade the client, that is a major inconvenient. # 2 I can 't restore the database with the option "-p". I did two different tests. A) The first backup was done with "onbar -b -L 0 -w" The restore was done via console with "onbar -r -w" It worked. But when I try to do "onbar -r -w -p", It failed. B) The second backup was done with all DBSpaces. The restore was done via console with "onbar -r -p". After I did "onbar -l" to apply logs (even if the LTAPEDEV=/dev/null). I received that message in the online file: DBspace logdbs not recovered from same archive backup as DBspace rootdbs. I would appreciate any help for these problems Thanks
