Questions Asked By Our Customers For The Ease Of Migration
Trusted by thousands of organizations all over the world
The following factors are important:
The throttling mechanism is used by Office 365 to ensure the avaiability of data security and services. Throttling mechanism imposes a limitation on the amount of data to be accessed by third-party applications. If you are migrating users without changing the throttling limit, there is a possibility of slower migration rate and high failure rate. It's highly recommended to increase the throttling before starting the migration. The recommended throttling value is 90 Days.
There are two options:
During the Office 365 tenant migration scenario, the mx record should not be changed in between the migration.
The Group mapping CSV contains the mapping of source users to destination users i.e. how the user id in source is mapped to the user id in destination. There is a likelihood of source user id being different in the destination platform. The group mapping CSV is referred by application while migrating Calendars and Documents.
Most of the times, the migration can be done in batches i.e. not all users are migrated at once. While exporting the calendars/documents, the migration engine uses the CSV to determine the destination userid of the source user found in calendar/documents and perform the task appropriately.If you don't provide it for the calendar migration then, user groups as attendees will not get exported. Similarly, if you don't provide it for the documents migration then, the shared list will not be migrated.
Yes, you can migrate the Users in Batches.
You can migrate the following:
Note: To migrate documents, permissions from source to destination accounts should be enabled by marking the “Migrate Document Permissions” option.
Basically, mapping will simplify the migration process. So, we recommend having all the user ids mapped in a CSV while migrating documents and calendars. If you are exporting documents, the user mapping is required to maintain the document sharing. If you are migrating calendars, then user mapping is required to maintain the attendees of an event.
Moreover, the software also provides “User Group Mapping option”. It allows to map the group from source to destination. The mapping between source group and its corresponding group is provided on the Users section.
No, SysTools Migrator does not support Team Drive Migration.
For any migration, whether small, medium or big, if the appropriate planning is not done then, it is bound to fail. It is highly recommended that appropriate planning is done for migrating data. Some of the important things to consider for planning are:
Capacity planning for migration is the determination of infrastructure required for migration. The important factor which the plan is derived on is:
We recommend using 1GB/user/hour as baseline for the speed of migration. The concurrency is set at 10 users at a time i.e. the migration engine takes 10 users for migration in parallel. Based on this, we can estimate that for a given machine it will migrate 240 GB per day.
Depending upon the expected timeline for migration, we can decide the number of machines. For e.g if we have to migrate 1 TB of data over a weekend, say, between Friday evening 6:00 PM to Monday morning 8:00 AM, then we need 5 machines to migrate the data.
The thing to note is that for large mailboxes, we have seen a deterioration of speed over a period of time. For a mailbox size of, say 100 GB, we may initially get a speed of 1GB/hour but over a period of time it reduces to 0.75 GB/hour or less.
Some other points to be considered for planning the Migration are
a) Migration of Multiple projects
b) Concurrent Migration.
Now, in the Settings option, the software provides two options which allow the user to fine tune the performance parameters for the migration. These are:
Two users licenses are provided for trial meaning that 2 user's data can be completely migrated using those 2 trial license.
No, there is no data limit in trial version.
To upgrade the SysTools Migrator trial version, you need to buy the full version of the tool. We recommend to use the same email id that is registered for the demo version while placing the order to avoid further troubleshooting.
System Requirements of the software:
Yes, we do support 100% migration unless there is a limitation of the destination platform which prevents the migration engine to export data.
Once the migration is completed for the User mailbox, the migration engine has the ability to transfer new data created in the mailbox after the migration has started. One of the most important things to be noted is that delta migration can be done only from the machine where the original migration was performed for the user. It is highly recommended not to uninstall the software unless the project is completed.
If you are migrating only emails and documents then, you need to define only emails and documents scopes. However, for authentication purpose, SysTools Migrator validates the scopes depending upon the selected workload.
No, It will migrate duplicate data to the destination account.
No, but if you have multiple projects then, the software provides an option i.e. “Enable multiple accounts”. It enables the user to configure multiple projects to be used for migration. If enabled, an icon to add multiple projects will appear on the source and destination screen. These multiple projects are useful for migrating a higher number of accounts concurrently on the machine with high-configuration.
Also, the software provides “Concurrent user” option. It enables the user to set the maximum number of users that will be migrated concurrently per project. That is, Number of Users in Migration = Concurrency Value * Number of Valid accounts.
Currently we are getting 1GB per hour. It is important to note that for large mailboxes, the speed may deteriorate as the data gets migrated. For example, for a 100 GB mailbox, the initial speed is 1 GB/hour but as the migration progresses, it reduces.
No, you have to manually click on the “Download Report” button to save the reports. The tool creates 2 types of reports including:
Note: The Summary Report and Detailed report will not be generated for pending accounts.
There are several cases in which the tool fails to maintain the folder hierarchy.
Yes, you can retry failed items. Once the migration gets completed, users can click on the “Retry Failed” button to migrate failed items.
Yes, you can reuse the same activation code for the same set of migrated users.
There are numerous logs generated by the SysTools Migrator tool. You can cross check the entire activity performed by the tool by checking the logs saved at the path C:\ProgramData\SysTools\WorkSpace.
Yes, you have to do pre-provision target OneDrive before migration. This is very important or else, the migration will not work.
The reason why users face this error is when you don't register the domain within the tool in SysTools CRM.
Yes, you can do that by executing the following steps:
There could be multiple reasons for validation failure as explained below:
