9. Migration network capacity Migration Velocity Testing – Understand your network and application usage o Microsoft Network Monitor o Microsoft Remote Connectivity Analyzer o Microsoft Online Services Diagnostics and Logging (MOSDAL) Support Toolkit Strategies to Improve Migration Velocity – To improve migration velocity as well as reduce your organization’s bandwidth constraints, you should consider the following: o Reduce mailbox sizes o Use the mailbox move capabilities with an Exchange hybrid deployment o Schedule mailbox moves to occur during periods of low Internet traffic and low on-premises Exchange use

11. Workstation configurations Steady-state network capacity Migration network capacity Workstation configurations NAT support Network performance factors Office 365 throttling Devices and multi-site configurations

12. Workstation configurations Each PC needs to connect to the Internet, download, and install any necessary service packs or updates Deploy updates via a package deployment tool such as Microsoft System Center Configuration Manager Alternatively consider Active Directory group policy or throttling your deployment of the Office 365 desktop setup

13. NAT support Steady-state network capacity Migration network capacity Workstation configurations NAT Support Network performance factors Office 365 throttling Devices and multi-site configurations

14. Network Address Translation support What is NAT? – Private (RFC1918) IP address space – Firewalls and proxy make traffic appear to be coming from one or more publicly routable IP addresses – Thousands of people on a corporate network can “share” a few publicly routable IP addresses NAT limitations with Office 365 – Outlook opens eight connections – There are a maximum of 60,000 ports available on a Windows-based NAT device

15. Network Address Translation support Calculating maximum supported devices behind a single public IP address with Office 365 – Monitor network traffic to determine peak port consumption per client o Maximum supported devices behind a single public IP address = (64,000 – restricted ports)/(Peak port consumption + peak factor) o If 4,000 ports were restricted for use by Windows and 6 ports were needed per device with a peak factor of 4: o Maximum supported devices behind a single public IP address = (64,000 – 4,000)/(6 + 4)= 6,000 To support more than 2,000 devices behind a single public IP address – Simplest solution is to segment your user address space and statically “assign” a number of IP addresses to each gateway

16. Network performance factors Steady-state network capacity Migration network capacity Workstation configurations NAT support Network performance factors Office 365 throttling Devices and multi-site configurations

17. Network performance factors Network capacity - Time it takes to migrate mailboxes to Exchange Online is determined by the available and maximum capacity of your network Network stability - If the network isn’t stable, data transfer takes longer because of error correction. Depending on the migration type, error correction can significantly affect migration performance Network delays - Intrusion detection functionality configured on a network firewall often causes significant network delays and affects migration performance

18. Office 365 throttling Steady-state network capacity Migration network capacity Workstation configurations NAT support Network performance factors Office 365 throttling Devices and multi-site configurations

19. Office 365 throttling Office 365 user throttling – User throttling affects most third-party migration tools and client-uploading migration method – User throttling is the most restrictive throttling method in Office 365 Office 365 migration-service throttling – Migration-service throttling affects all Office 365 migration tools – An example of migration-service throttling is controlling the number of mailboxes that are migrated simultaneously, default value is 3 Office 365 resource health-based throttling – All migration methods are subject to the governance of availability throttling, but Office 365 service throttling doesn’t affect Office 365 migrations as much – Resource health-based throttling is the least aggressive throttling method

20. Devices and multi-site configurations Steady-state network capacity Migration network capacity Workstation configurations NAT support Network performance factors Office 365 throttling Devices and multi-site configurations

21. Devices WAN Accelerators – WAN accelerators are great when you control both ends of the traffic. – When you aren’t planning half the traffic WAN accelerators are hard to deal with. o For example, Office 365 services encrypt some Office 365 content and the TCP header. Your device may not be able to handle this kind of traffic. Hardware and Software Load-balancing Devices – You may want to use a load balancer if you have AD FS or any SSO solution – We provide a software-based NLB solution built into Windows Server. Office 365 supports this solution to achieve load balancing.

22. Multi-site configurations Client computers may connect to different Office 365 datacenters – Computer location, VPN, DNS, Office 365 service, and so on. – Customers have some control – Different connections will have different performance attributes
