Hi,
We try to upgrade Exchange 2013 to Exchange 2016, and in meanwhile migrate EV12.4 to EV14.4 with new OS and MSSQL server. In-place upgrade is not an option for us as there are risks to lose data (4TB size). We currently only do mailbox archive, no journal archiving or files archive.
I would like to know can we:
1. Install a new EV14.4 site and link it to Exchange 2016;
2. Migrate 1 user mailbox from EX13 to EX16;
3. Use "Moving Archives" function move archive from EV12 to EV14;
4. Repeat all steps until we done the migration.
On the other hand, I read the document and it indicates that we cannot use "Moving Archives" for "Closed Archives". We do have 3 partition in same group, 2 are closed and 1 is currently open. So it means we can't use "Moving Archives"?
Please kindly advise, we do need a suggestion here, thank you so much!
Below is our target:
From EV12.4:
- OS: Win 2012 R2
- MSSQL: 2012
To EV14.4
- OS: Win 2019
- MSSQL: 2019

Hi Tonaco_pt,
Thank you for sharing your notes, I wanna confirm if I understand your steps correctly:
1. Add a new EV12.4 server with exact same spec as the old one, and add it to the same site.
2. Move only all services to the new EV12.4, and in-place upgrade to EV14.4;
3. Install new EV14.4 with the new Windows Server 2019 and MSSQL 2019;
4. Migrate the upgraded EV14.4 services to new EV14.4;
I have some questions about the steps' detail:
1. When adding new EV12.4 to same site as old one, can we config using same VaultStore and Indexing?
2. There are 2 EV12.4 server in one site, can I only upgrade one of them to EV14.4? Can different version of EV stay in one site?
3. As my old EV12.4 is using MSSQL 2012, EV14.4 is not support. How can I do the in-place upgrade?
4. After upgrade the EV14.4, will it affect the old EV12.4 server archived data or index? As EV14.4 is using new index system ElasticSearch.
5. When all solved, Install the new EV14.4 with all new spec in a new site, then start to migrate storage, indexing and server setting? What are detail steps for storage and indexing migration?
I might need more details steps to understand better, thank you again for your kindly sharing!

Hi Tonaco_pt,
Sure please reply to me at your convenient.
We would like to do the EV upgrade with Windows Server and MSSQL server at the same time.
I think it is better to do a migration upgrade instead of inplace upgrade in order not to affect current data and environment.

I would personally first upgrade/move EV to 14.4, then upgrade to new SQL version. If something goes wrong, it is easier to troubleshoot what is not correct. If you do everything in 1 go, you introduce a risk that Os, or EV, or SQL or all are not ok. Step by step is better way.
I wrote a few articles on moving database, upgrading etc. They can be found under my profile on LinkedIn.

Hi,
When I upgrade, this where my assumption:
We had a 2 node Cluster in Windows 2008 R2, our SQL Server (2008) was one group of the cluster and we end up with a 4 node cluster in windows 2019 and SQL 2019.
That why we had the extra step.

Hi both,
Thank you for both of your opinions. I have come up an idea of a simplest solution for me, can you give your opinion on this? With this plan, I don't need to do in place upgrade or migrate database. All indexing should re-build in new EV14.
Simply say, I want to separate the old EV12 and new EV14 in complete 2 new sites, and migrate archive one by one using:
Initial plan to do:
But I wanna know:
Many thanks and regards,

Hi,
NOTE: Old shortcut will not work. If you Archive date become the date of PST import and there will be other issue, I never did this approve, I read about but went another way, don't remember way (I know had to do with date of archive) .
