Re: Best practice: Upgrade OS and Cell Manager

because DP 6.11 can be installed as cell server on a 2008 R2 server, i suggest you doing the following (easiest way):

 

Install new Server with 2008 R2

Give it the same hostname if possible

Install DP 6.11 into the same directory

install the same DP 6.11 patches

stop dp services on old and on new server

copy omniback\db40, omniback\config, omniback\omnirc to the new server

start dp services on new server

now you have the same idb as on the old server. check if everything is ok (omnidbcheck)

if you dont have the same ip on the new server, you have to migrate licences... i suggest you do this before you migrate.

 

then you can update to 7.0, after to 7.01 or 7.03

 

i suggest you check if all server os and application you need to backup are still supported with 7.x version.

 

hope this helps

 

if you change ip or hostname or install path, aditional steps are required...

Re: Best practice: Upgrade OS and Cell Manager

Hi,

Thanks.
Well, first difference could be:
D:\Program Files\OmniBack on windows 2003
and
D:\ProgramData\OmniBack on windows 2008.

What about folder: omniback\omnirc
I don't have it.

If we decide to change hostname, will it be more complicated then using command:
omnidbutil -change_cell_name


Thanks & Regards,

Re: Best practice: Upgrade OS and Cell Manager

well i would never install data protecot into the c drive... i remember some years back when i've spoken to a dp teacher he also told me best practice is not to install dp on c drive. (file system fragmentation, performance and so one) every installation i do, i have an additional disk for example E drive and install it there. (E:\Omniback - no splitting between programdata and program files)

 

no there is no problem using the omnidbutil -change_cell_name. used it often, worked fine.

 

well if you decide to install dp on the new server into a different direcotry (as i mentoined above) then you cant just copy folder db40. you have to export the idb

 

omnidbutil -writedb -mmdb <path> -cdb <path>

on the new server you can do your installation into e:\omniback. then check that you have enought fnames and extension files for importing the idb again. if everything is alright, you can do an omnidbutil -readdb -mmdb <path> -cdb <path>. then do the change_cell_name. then you have to relocate the dcbf (Detail catalog binary files) directory. i think that was already discused in the forum...

 

hope this helps

Re: Best practice: Upgrade OS and Cell Manager

HI,

and why not:
1. Upgrade Cell Manager from 6.11 to 7.00 (after to 7.01 or 7.03)
2. Migrate Cell Manager from Windows 2003 R2 to Windows 2008 R2?

Thanks,
Tom

Re: Best practice: Upgrade OS and Cell Manager

this is a way you could do as well. but then i would suggest update existing cell server to 7.0 -> 7.03 and leave it running several days to look if everything is fine. then migrate. otherwise if you update and migrate the same day and you have troubles on the new cell server, you wont know if they come from the migration or the version update.
