Hello All,
We are trying to perform an upgrade of our Remedy Instance on v5.01.01 to
v8.1.
So far we have upgraded ARS from v5.1.2 > v6.3 > v7.1 > v7.6.04.(Solaris)
on Dev Environment as a proof of concept.
We are targeting to Upgrade to v8.1 and also to move to Linux(VMware ESX).
To accomplish this here's what we are trying to do:
1. Upgrade ARS to v7.6.04(Solaris), take DB(10g) copy
2. Install a fresh ARS of v7.6.04(Linux) + DB(10g)
3. Drop DB of Step 2 + Attach DB copy from Step 1(so we will have a ARS
v7.6.04 with Linux on 10g DB)
4. Upgrade DB to 11g
4. Run upgrade install from ARS v7.6.04 to v8.1
Based on the above approach/ steps I have few questions:
1. Is the above approach feasible?, as the aim for our upgrade is to bring
our Remedy instance to a supported version.
ARS upgrade from v5.1.2 to v8.1. Also, we would like to move away from
Unix/Solaris platform to Linux VM platform.
2. We also have ITSM 5.6/Remedy HelpDesk v5.1.2 - How do we handle this? As
for now, we are only thinking of upgrading ARS not ITSM.
3. Also, my understanding is v7.5 onwards, there has been drastic changes.
Any caveats of losing our customizations(Customization on HPD as well as
Custom applications we have in place)? How do we handle these?
4. Dev Server - As a proof of concept on our Dev Server, we upgraded ARS
from v5.1.2 to v7.6.04 so far. Working on to upgrade to v8.1 now.
5. DB from non-unicode to unicode - Our Dev DB was already Unicode. Whereas
our Prod DB is non -unicode, so at what point do we have to convert from
non-unicode to Unicode(before running v6.3 Upgrade install)?
Source - ARS v5.1.2 + ITSM v5.6(HelpDesk v5.1.2) + Custom/Home grown apps.
Destination/Target - ARS v8.1 + ITSM v5.6(HelpDesk v5.1.2) if supported or
ITSM v8,1(Service Desk) + Custom/Home grown apps.
Environment Information:
Current Production:
Environment Info:
AR Server Version : 5.01.02 Patch 1313
Hardware : sun4u
Operating System : SunOS 5.10
DB : SQL -- Oracle
DB Version : 10.2.0.5.0 - 64bi
Current Development (where we are running ARS Upgrade Installs):
Environment Info:
AR Server Version : 7.6.04 SP4 201209051922
Hardware : sun4u
Operating System : SunOS 5.10
DB : SQL -- Oracle
DB Version : 10.2.0.5.0 - 64bi
Does the above approach feasible? I would highly appreciate any
help(practical lessons, gotchas, caveats, etc) you can provide.
Regards,
Raj
