查看迁移进度

Get-MoveRequest -MoveStatus inprogress | Get-MoveRequestStatistics | Sort-Object -Descending PercentComplete | ft displayname,statusdetail,percent*,sourcedatabase -AutoSize -Wrap

2010迁移2016进度：

$allmailbox=Get-Mailbox -ResultSize Unlimited
$迁移进度=$($allmailbox |?{$.AdminDisplayVersion -like "15.1"}|Measure-object).Count/$allmailbox.Count
$迁移进度="{0:P2}" -f $迁移进度
Echo "
迁移进度：$迁移进度，已完成人数：$($($allmailbox |?{$.AdminDisplayVersion -like "15.1"}|Measure-object).Count)人，总数：$($allmailbox.Count)人
"

迁移

整库迁移

Get-Mailbox -Database 源库 |New-MoveRequest -TargetDatabase 目标库 -BadItemLimit 500 -AcceptLargeDataLoss -Debug -Verbose -SkipMoving:folderviews,folderrestrictions

导出用户（用于统计用户配额是否满足迁移需求 与 用户迁移通告）

$dataname="目标库"
Get-Mailbox -Database $dataname |select Name,Alias,ProhibitSendReceiveQuota,PrimarySmtpAddress |Export-Csv -Path D:\迁移用户\aaaa\$dataname.csv -NoTypeInformation -Encoding UTF8

过滤绝大部分失败命令：

$users=Import-Csv D:\迁移用户\aaaa\DatabaseUser.csv -Encoding Default
foreach($user in $users){
get-mailbox -id $user.Alias |New-MoveRequest -TargetDatabase Other-System-SSD901-02 -BadItemLimit 500 -AcceptLargeDataLoss -Debug -Verbose -SkipMoving:folderviews,folderrestrictions
}

注：DatabaseUser.csv为导出的文件

查看失败错误信息

Get-MoveRequest |?{$.Status -like "Failed"}|Get-MoveRequestStatistics|select Alias,Message
Get-MoveRequest |?{$.Status -like "Failed"}|Get-MoveRequestStatistics|fl Alias,RequestQueue,Message

查看配额失败列表信息

$moverequest=Get-MoveRequest |?{$.Status -like "Failed"}|Get-MoveRequestStatistics|select Alias,Message
$mrequests=@()
Foreach($mrequest in $moverequest){
$size=@()
$size=$mrequest.Message -split "Size: '"
$size =$size[1].Split("(")[0]
$quota=@()
$quota=$mrequest.Message -split "Quota: '"
$quota=$quota[1].Split("(")[0]
If($size)
$mrequests+=$mrequest|select Alias,@{Name = 'size'; Expression = {$size}},@{Name = 'quota'; Expression = {$quota}}
}
$mrequests

处理失败项目的重新迁移命令

$user=@()
$failedusers=Get-MoveRequest |?{$.Status -like "Failed"}
Foreach($user in $failedusers){
Remove-MoveRequest $user.DisplayName -Confirm:$false
