1. Backup the MYOB AO data on old server/standalone
  1. Backup the SQL databases :
    1. AODB1 and AOTAX1 using SQL Management Studio. For more information refer to KB 33978: Backing up a SQL database using Management Studio
    2. To backup the ELS and SBR folders, open windows explorer and navigate to the AOSQL\Tax\TA\<db_name> folder and copy the ELS and SBR folders.
      Note: Where <db_name> is the name of the tax database i.e AOTAX1, AOTAX2 etc.
  2. Take these backed up files off the server onto either the new server or a device to copy it over to the new server, such as a USB stick.
Backup of templates and client documents

If using Document Manager or Corporate Compliance

Document Manager: Backup of Document Manager and Intranet File Stores.Refer to Backing up MYOB Document Manager files. Please note All documents must be checked in prior to copying data. For details refer to KB 23570: How do I view a list of all checked out documents?
Corporate Compliance: Backup of Corporate Compliance SQL databases.Refer to Performing a backup or restore of Corporate Compliance. Also copy across your ELS folder CC > Help>About CC > Application Details > Electronic Lodgement Path.

Take these backed up files off the server onto either the new server or a device to copy it over to the new server, such as a USB stick.

Locating your templates and documents

In MYOB AO navigate to the Maintenance menu > Maintenance Map > Documents. Note down any relevant paths under the following areas:

Document settingsNote this path
Document Creation Settings
  • Tax Receipts Algorithm
  • VAT Receipts Algorithm
  • Word Billing Algorithm
Mailing Settings
  • Billing Startup Path
  • Templates Path
  • Document Startup Path
Document Styles
  • All selected styles

If these paths are still in use and you're unsure what these paths are for, refer to the help menu. Make sure the files in these locations are copied across to the new server.

2. Pre-configuration and MYOBAO Data copy

Standalone install pre-configuration

  • Create MYOBAO folder on C:\ drive
  • Copy the data folder from old PC into C:\MYOBAO\ folder.
    Rename the AOSQL to AOSQL.old folder within the MYOBAO folder.

Network install pre-configuration

  • Create the AONET directory to store MYOB AO program and data files. This can be located anywhere on the server machine. You will need to refer the installer to this location later.
  • AONET must then be shared and mapped as a network drive on the server and all workstations.
  • You will also need to copy MYOBAO folder to the AONET folder. Inside MYOBAO folder, rename AOSQL folder to old. 
3. Copy Document Manager and Intranet File Stores (if using Document Manager)

Document Manager

Intranet File Store

  • The Intranet File Store folders must be copied to the default location M:\MYOBAO\AOSQL\Knowledge Management\Intranet\Data (Where M:\ is the mapped drive for AONET share). You will have to first manually the create folders for Knowledge Management\Intranet\Data under the AOSQL folder.

If you copy over the Databaselookup.XML file that exists in both your DMFS and Intranet Data folder, you'll need to delete both XML files before you run the installer. If you have multiple MYOB AO databases, you may also have multiple file stores. Ensure these are brought across as well. For example, DMFS_AODB1, DMFS_AODB2
