SEP 11 to SEP 12.1 RU2 Migration WITH SQL
I am currently preparing to migrate from SEP 11.0.7000.975 to SEP 12.1 RU2. Our environment does not run off of the embedded database as we use a separate server running SQL.
I have read through all the documents and taken classes on SEP 12 and most everything in all documentation is for the embedded db only. What happens with SQL?
I am planning on building a separate SQL server and 2 new SEPM consoles. We will back up the database and restore to the new SQL server. Then install SEP 11 to the new servers and perform disaster recovery. Once running we will upgrade to SEP 12.1 RU2 and then use the sylink mover to get all the 11 clients moved to the new server.
This seems to be the easiest way with fall back plan is to put clients back on the old infrastructure. However there is no real documentation on this or any other knowledge for SQL installation types I have found. Everything I have read may mention SQL but then just goes into embedded database structure. I have over 35000 clients. I can't do embedded. One huge question on this is that everything states that the db will increase 3x during migration. It also states for embedded only. Is this true? Will my SQL also expand to 3x with the migration to 12? What other issues will we have by doing this? I know we can't access the 12 database from 11 management consoles or it will corrupt the database. Is there any other restrictions to doing this?
Any help would be much appreciated.
