Sometime there could be requirement where we wants to move certain amount of data out of a database, below script is helpful where we wants to calculate how many mailbox fill in the required amount of Data and then wants to put them on move request.
below are the parameters required.
Usage Examples:
# Get the no of Mailbox and there list only.
>GetMbxToMoveFromDB -SDB TestDB -SizeToMoveInGB 100
# Sort the Mailbox based on the Size and Get the no of Mailbox and there list only.
>GetMbxToMoveFromDB -SDB TestDB -SizeToMoveInGB 100 -Sort True
# Get the no of Mailbox and place them on Move below command will move 100 GB out of TestDB
>GetMbxToMoveFromDB -SDB TestDB -SizeToMoveInGB 100 -move $true -Tdb TestDB2 -MRS CAS1 -BIL 10
# Sort the Mailbox based on the Size and Get the no of Mailbox and there list only.
>GetMbxToMoveFromDB -SDB TestDB -SizeToMoveInGB 100 -move $true -Tdb TestDB2 -MRS CAS1 -BIL 10 -Sort $True
below are the parameters required.
[int]$SizeToMoveInGB, # Size of DATA in GB like 100 GB
$sDB, # Source Database
$sort, # to sort mbx based on size.
$TDB, # Target Database
$move=$false, # to place the Mailbox on Move
$MRS, # to assign MRS instance Server for move request
$BIL # Bed Item Limit
Usage Examples:
# Get the no of Mailbox and there list only.
>GetMbxToMoveFromDB -SDB TestDB -SizeToMoveInGB 100
# Sort the Mailbox based on the Size and Get the no of Mailbox and there list only.
>GetMbxToMoveFromDB -SDB TestDB -SizeToMoveInGB 100 -Sort True
# Get the no of Mailbox and place them on Move below command will move 100 GB out of TestDB
>GetMbxToMoveFromDB -SDB TestDB -SizeToMoveInGB 100 -move $true -Tdb TestDB2 -MRS CAS1 -BIL 10
# Sort the Mailbox based on the Size and Get the no of Mailbox and there list only.
>GetMbxToMoveFromDB -SDB TestDB -SizeToMoveInGB 100 -move $true -Tdb TestDB2 -MRS CAS1 -BIL 10 -Sort $True
