FAQ: FirstClass to Office365 Migration Services

What message attributes are included for converted content?
The migration process captures the following message fields:
  • To
  • From
  • Cc
  • Subject
  • Body
  • Attachments
  • Time/Date
Is there any limit to the number of messages that can be migrated?
There is no limit to the number of messages that can be migrated.

Is there any limit to the size of an account that can be migrated?
There is no limit to the size of an account that can be migrated.

Is there any limit to the size of messages that can be migrated?
Microsoft allows import of messages up to 200MB. Any messages larger than this will be moved into a folder called "Large messages" on the user's FirstClass desktop prior to the migration process.

Does the migration capture both inbound and outbound mail?

Does the migration capture mail filed in folders?

Does fcExport capture mail filed in nested folders?
In preparation for the migration process we run a process to "flatten" the folder structure.  This ensures that all mail gets migrated, even for folders originally stored several layers down. For example, suppose you have a mailbox with the following structure:

 |    |--2013
 |    |--2014
 |    |--2015

Prior to migration the FirstClass folders would be adjusted to:


The "flat" folder structure is what gets created within O365

Does the migrated content support both traditional and "threaded" views in O365?
Imported content does not support the threaded view in O365, and will be presented using the traditional list view.

Does the migration process capture the Internet address associated with FirstClass user names?
Yes, so long as the user account exists at the time of migration. We use the Internet address assigned on the Aliases field of the User Information Form, allowing your exported messages in O365 to show Internet Addresses for FirstClass users.

In some circumstances, such as receipt of a message addressed to a mail list, or receipt of a message from a user no longer present in FirstClass, no Internet address will be available to the migration tools and a placeholder address will be constructed so the message can be migrated.

How quickly does mail get migrated?
Exact performance varies depending on account size, FirstClass hardware capacity and configuration.  In most environments we can migrate 25-50 accounts per day.

Can you guarantee 100% fidelity of the migrated content?
No, we can't.

In general the accuracy and completeness of migrated data is quite good, and we make every reasonable effort to ensure the best possible data accuracy. We cannot, however, guarantee 100% fidelity. Due to a variety of factors, from FirstClass platform limitations or corrupted items in the FirstClass network store, to O365 API issues or unanticipated changes on Microsoft policy or software, there is a possibility that some messages may may not come through, or may not be represented with 100% fidelity. Historically we see an error rate of approximately 0.02%

How do you determine the destination account for each user?
As part of the migration process we ask for a mapping of FirstClass userID to the email address of the target O365 account.

Will the export process work against a FirstClass Server running OS X?
Yes.  The FCAS and O365 upload components of the migration tools need to be installed to a Windows server, which can connect to a host machine running under OS X, Linux, or Windows. Note that performance against OS X and Linux is slower than in a Windows environment, so timing may need to be considered for large migrations.

How does the mail get into O365? do you need O365 account credentials?
There is some configuration we do up-front using an admin-level domain account in O365.  This allows us to configure the O365 Import API and Microsoft's Azure tool for uploading content.  There's no need to share end-user credentials on either the FirstClass or the O365 side of things.

Do you have to provide the migration as a service, or can we just purchase the tool and do the migration ourselves?
We strongly recommend mail migration as a service rather than just providing the tool (although we can consider that if needed).  The reason is that the migration of mail is a one-time activity for you.  We've done this a bunch of times and have gotten good at knowing how to avoid pitfalls and doing the migration as efficiently as possible.  By providing this as a migration service we're able to significantly reduce your frustration and time, so you can focus on other aspects of your conversion.

Can you migrate conferences?
Yes, we can export messages from conferences and map these to user accounts in O365 for import.  Note that the migration process will only export messages, not uploaded files or objects of other types.

Can you migrate Contacts?
We can produce a .csv export of Contacts for each user if desired.  Contacts are not imported automatically into O365.

Contact exports include all fields present in the FirstClass contacts form, and are provided with headers recognized by Outlook and O365 for import purposes.

Can you migrate Calendars?
We can produce a .csv export of Calendars for each user if desired.  Calendars are not imported automatically into O365.

Calendar exports are provided with headers recognized by Outlook and O365 for import purposes.  Note, however, that details regarding event repeats are not read, so imported calendar events will only include the first instance of any repeating event.

 How well does the migration process work with UTF-8 content in FirstClass?
Extended 8-bit characters work just fine in both message subjects and bodies.  32-bit characters come through fine in bodies, but are not supported in subject lines or for folder names.  Extended characters in subject lines or folder names are omitted in the exported content, or converted to similar ASCII characters.
