We have a production setup running Lync 2010 Standard Edition with Edge and Proxy.

We need to migrate from Front End Standard to Enterprise version on a new server also we will change the server for edge with a new one.

We need to understand what is the best approach to deal with this scenario

1.To uninstall the Lync setup from the existing server and start fresh.

2.Migrate the standard pool from the old server to the enterprise pool created on the new server.

This will help us in settling conflicting viewpoints and plan the correct and recommended approach.

Hi,

Side by side migration is recommended. Means , you should deploy a EE pool parallel and migrate the users from standard edition to EE pool. Also migrate CMS database once users have been moved. Once you finish the migration , you can decommision old standard edition server.

Thanks

Hi Shireesh1,

If it standard but you don't have users data or something you want to keep , The easy way is to uninstall then start new one , As I did before many times with some production on few users.

but if there if there is enterprise voice or much data on users side and configuration , I will go for Saleesh suggestion.

Sorry Ahmed i cannot follow your first idea.

it is NOT the easy way to uninstall and reinstall. it easy but you loose buddies, Conference data and many more. and you have a downtime of some hours (if everything works fine) but if you want to move to enterprise, you have to install two server, maybe a HTTP loadbalancer, the SQL-Cluster in the Backend. this takes time if you do it right, with documentation, verification etc etc. And if someone made the decision for enterprise, they are looking for high availibilty or scaling.

It is always better to doe a side by side migration. But of course you have to be carful with the Edge, certificates, simple URLs.

Sometimes i had to uninstall a standard lync because it was a "test in production" stuff and i was no problem to remove it for some days and start from fresh. But thats happens not very often.

BTW it's time to think about Lync 2013 :-)  so thats a Side by Side migration., too :-)

Hi,

Agree with Saleesh. It is recommended to migrate the standard to enterprise pool. In this case, you need to keep you Standard pool to work and deploy new Enterprise pool with only one Front end server. It don't have DNS load balance. After migrating the users, CMS database and decommission old standard edition server, you can add this old server into Enterprise topology as an front end server of EE pool and then install it to use DNS load balance.

Thank you all ,

We will go with side by side migration but as I see Lync 2013 has entered RTM and is available at MSDN for download, we have this one to try as well before we go further.

Hi Saleesh,

Can I know what is the best option to make side-by side, but there is changes on Hostname and IP address.

Thank you.
