LL 9.1 upgrade to 9.5 Need answer ASAP!

[nononame]

Hi,

we need to upgrade LL 9.1 to 9.5.

How complex this work is?
How long can it take? few days? a week? two weeks? more?

can this be done by an experienced programmer who just can follow the detailed instructions or do we need to hire LL professionals?

Our application is bilingual.

Does any one have experience?
Any tips and advice are appreciated!

thanks!

I replied to your opentext thread like this
**********************************************

First you have to visit the knowledge base

https://knowledge.opentext.com/know...4040153/customview.html?func=ll&objId=4040153

Make sure the hardware requirements are met,the upgrade path as identified as in the release notes .For eg when I had to upgrade form 9.10.sp3 to 9.5sp1,I had to do a intermediate upgrade to 9.1sp4 and then to 9.5 sp1.all said and done it took only 3 hrs to get the db upgraded.
We brought up production in less than 6 hours I believe.
This was after endless upgrade testing I believe I tried ( 3 times on a test system) to work the kinks over.You need to test core upgarde,moduel upgarde,any depedencies all kinds.
Finally after the upgrade was done realized did not meet the HW reqs for searching so was without search for one and a half months(BTW:we were probably one of the first who upgraded)
The searching part is not at all straightforward but you will get a lot of help from this forum
Can this be done by a programmer,depends if your programmer knows livelink,webservers,databases as they are all needed to make this work.
Usually a livelink upgrade does not happen like without planning,even though most of the steps are "Next"-"Next" kind of things.Finally I have no experience in a bi-lingual livelink or a livelink that runs on application servers.

Hope all this helps you in your endeavour

There is a very good section on the KC (

https://knowledge.opentext.com)

about upgrading to 9.5, if you are currently on 9.1SP3 or lower then you will need to upgrade to 9.1SP$ prior to upgrading to 9.5SP1.

Generally OpenText provide staff to do the upgrade for you, is there any reason why you are not doing it this way ?

If you have to do the upgrade yourself then I would use/create a demo system that you can upgrade and test prior to doing it on production.

Also ensure that you have all the Livelink modules that you require for your multilingual installation.

Hi Greg,
"Generally OpenText provide staff to do the upgrade for you, is there any reason why you are not doing it this way ? "
I am not sure what you meant by this.Our customer support agreement does not buy us this.Are you on a "golden" kind of arrangement with OT .I have heard OT has differing kinds of support.All our support does is give us the software,phone or email support for a specialist,and we are pretty much on our own when upgrading.OpenText Professional services are very costly in the range of (> $1800 per day).Is that what you meant?

We have just upgraded from 9.2 to 9.5 with only a few problems with the upgrade itself. We testing the upgrade some 5 times before running on the live system. However, we had a huge problem with the re-indexing and indeed this is still ongoing. Some PDFs are indexed and some aren't.
As for doing it ourselves, this was considered the preferred option to ensure we controlled the method. However, we had an OpenText consultant onsite during the upgrade.

We have had OT in to do upgrades for some of our customers and we have paid for them to be onsite in addition to our standard support contract, if you have a complex install the extra knowledgable pair of hands can be helpful.

Hi All,
You mail seem to suggest migrating is fast but :
What about custom developments ? (Oscript / LAPI)
What about Search slices ?
What about search templates ?

Are they upgraped without any problems ?
Or do you need to rewrite all ?

Additonaly, what is the interruption of service minimum length ? (I guess i can accept the index being rebuilt while service is back)
Supposing I cannot anticipate in any way as there are content being added until the lsat minute...

regards

 

[ggriffit]

Any custom developments will need to be rebuilt against 9.5 and retested prior to an upgrade, as for the Search and Index stuff you will need to either migrate your indexes or rebuild them from scratch completely as part of the upgrade.

I checked our custom oscripts and there was very few changes.You don't even need the SDK all it took was change a line to reflect the new kernel.Vended lapi applications failed first because it was not part of lapi's fault,but when 9.5sp1 came out it leaked memory on allocating connections.Once we reported that and OT fixed it all vended lapi(kofax,authorlink,llexplorer,ignite) apps that was supplied for 91.sp3 did work.We rebuilt our search from scratch after analyzing the old index.Like Greg said it is a complex system and better test all your dependencies before going live.By far in my experience(I have seen llsystems back in 8.1.5) it was the most easy upgrade I have ver performed.

thanks to all for valuable answers!

ggriffit, how long did upgrade take for you? (in hours?)
we have a number of web reports, will it make upgrade/app tuning more complex?

Hi,

We tried to upgrade to 9.5 from 9.1. The upgrade procedure seems easy, but the issue is with indexing. We could not migrate neither could we build new index. Building new index takes a long long time. More than a week. We decide to upgrade to 9.2 first and then, when 9.5 version has stabalized we will probably upgrade to 9.5.

Hope this helps

 

[ggriffit]

vshinde is correct that on average the most time consuming component of a 9.X->9.5 upgrade is the indexing changes that are part of 95.

VShinde, can you explain why you could not migrate or recreate your indexes ?

I am reasonably sure that 9.6 will be launched Q1/Q2 this year and apart from the indexing issue I am very happy with LL9.5SP1.

In our experience, getting the third party custom modules upgraded took the most time.
Make sure if you have third party modules (even OT professional services ones), that you get them upgraded and tested asap. Then make sure again that your supplier actually tested the module against the correct livelink version.
