function Rename-DbaDatabase { <# .SYNOPSIS Changes database name, logical file names, file group names and physical file names (optionally handling the move). BETA VERSION. .DESCRIPTION Can change every database metadata that can be renamed. The ultimate goal is choosing to have a default template to enforce in your environment so your naming convention for every bit can be put in place in no time. The process is as follows (it follows the hierarchy of the entities): - database name is changed (optionally, forcing users out) - filegroup name(s) are changed accordingly - logical name(s) are changed accordingly - physical file(s) are changed accordingly - if Move is specified, the database will be taken offline and the move will initiate, then it will be taken online - if Move is not specified, the database remains online (unless SetOffline), and you are in charge of moving files If any of the above fails, the process stops. Please take a backup of your databases BEFORE using this, and remember to backup AFTER (also a FULL backup of master) It returns an object for each database with all the renames done, plus hidden properties showing a "human" representation of them. It's better you store the resulting object in a variable so you can inspect it in case of issues, e.g. "$result = Rename-DbaDatabase ....." To get a grasp without worrying of what would happen under the hood, use "Rename-DbaDatabase .... -Preview | Select-Object *" .PARAMETER SqlInstance Target any number of instances, in order to return their build state. .PARAMETER SqlCredential Login to the target instance using alternative credentials. Accepts PowerShell credentials (Get-Credential). Windows Authentication, SQL Server Authentication, Active Directory - Password, and Active Directory - Integrated are all supported. For MFA support, please use Connect-DbaInstance. .PARAMETER Database Targets only specified databases .PARAMETER ExcludeDatabase Excludes only specified databases .PARAMETER AllDatabases If you want to apply the naming convention system wide, you need to pass this parameter .PARAMETER DatabaseName Pass a template to rename the database name. Valid placeholders are: - <DBN> current database name - <DATE> date (yyyyMMdd) .PARAMETER FileGroupName Pass a template to rename file group name. Valid placeholders are: - <FGN> current filegroup name - <DBN> current database name - <DATE> date (yyyyMMdd) If distinct names cannot be generated, a counter will be appended (0001, 0002, 0003, etc) .PARAMETER LogicalName Pass a template to rename logical name. Valid placeholders are: - <FT> file type (ROWS, LOG) - <LGN> current logical name - <FGN> current filegroup name - <DBN> current database name - <DATE> date (yyyyMMdd) If distinct names cannot be generated, a counter will be appended (0001, 0002, 0003, etc) .PARAMETER FileName Pass a template to rename file name. Valid placeholders are: - <FNN> current file name (the basename, without directory nor extension) - <FT> file type (ROWS, LOG, MMO, FS) - <LGN> current logical name - <FGN> current filegroup name - <DBN> current database name - <DATE> date (yyyyMMdd) If distinct names cannot be generated, a counter will be appended (0001, 0002, 0003, etc) .PARAMETER ReplaceBefore If you pass this switch, all upper level "current names" will be inspected and replaced BEFORE doing the rename according to the template in the current level (remember the hierarchy): Let's say you have a database named "dbatools_HR", composed by 3 files - dbatools_HR_Data.mdf - dbatools_HR_Index.ndf - dbatools_HR_log.ldf Rename-DbaDatabase .... -Database "dbatools_HR" -DatabaseName "dbatools_HRARCHIVE" -FileName '<DBN><FNN>' would end up with this logic: - database --> no placeholders specified - dbatools_HR to dbatools_HRARCHIVE - filenames placeholders specified <DBN><FNN> --> current database name + current filename" - dbatools_HR_Data.mdf to dbatools_HRARCHIVEdbatools_HR_Data.mdf - dbatools_HR_Index.mdf to dbatools_HRARCHIVEdbatools_HR_Data.mdf - dbatools_HR_log.ldf to dbatools_HRARCHIVEdbatools_HR_log.ldf Passing this switch, instead, e.g. Rename-DbaDatabase .... -Database "dbatools_HR" -DatabaseName "dbatools_HRARCHIVE" -FileName '<DBN><FNN>' -ReplaceBefore end up with this logic instead: - database --> no placeholders specified - dbatools_HR to dbatools_HRARCHIVE - filenames placeholders specified, <DBN><FNN>, plus -ReplaceBefore --> current database name + replace OLD "upper level" names inside the current filename - dbatools_HR_Data.mdf to dbatools_HRARCHIVE_Data.mdf - dbatools_HR_Index.mdf to dbatools_HRARCHIVE_Data.mdf - dbatools_HR_log.ldf to dbatools_HRARCHIVE_log.ldf .PARAMETER Force Kills any open session to be able to do renames. .PARAMETER SetOffline Kills any open session and sets the database offline to be able to move files .PARAMETER Move If you want this function to move files, else you're the one in charge of it. This enables the same functionality as SetOffline, killing open transactions and putting the database offline, then do the actual rename and setting it online again afterwards .PARAMETER Preview Shows the renames without performing any operation (recommended to find your way around this function parameters ;-) ) .PARAMETER WhatIf If this switch is enabled, no actions are performed but informational messages will be displayed that explain what would happen if the command were to run. .PARAMETER Confirm If this switch is enabled, you will be prompted for confirmation before executing any operations that change state. .PARAMETER InputObject Accepts piped database objects .PARAMETER EnableException By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message. This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting. Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch. .NOTES Tags: Database, Rename Author: Simone Bizzotto (@niphold) Website: https://dbatools.io Copyright: (c) 2018 by dbatools, licensed under MIT License: MIT https://opensource.org/licenses/MIT .LINK https://dbatools.io/Rename-DbaDatabase .EXAMPLE PS C:\> Rename-DbaDatabase -SqlInstance sqlserver2014a -Database HR -DatabaseName HR2 -Preview | Select-Object * Shows the detailed result set you'll get renaming the HR database to HR2 without doing anything .EXAMPLE PS C:\> Rename-DbaDatabase -SqlInstance sqlserver2014a -Database HR -DatabaseName HR2 Renames the HR database to HR2 .EXAMPLE PS C:\> Get-DbaDatabase -SqlInstance sqlserver2014a -Database HR | Rename-DbaDatabase -DatabaseName HR2 Same as before, but with a piped database (renames the HR database to HR2) .EXAMPLE PS C:\> Rename-DbaDatabase -SqlInstance sqlserver2014a -Database HR -DatabaseName "dbatools_<DBN>" Renames the HR database to dbatools_HR .EXAMPLE PS C:\> Rename-DbaDatabase -SqlInstance sqlserver2014a -Database HR -DatabaseName "dbatools_<DBN>_<DATE>" Renames the HR database to dbatools_HR_20170807 (if today is 07th Aug 2017) .EXAMPLE PS C:\> Rename-DbaDatabase -SqlInstance sqlserver2014a -Database HR -FileGroupName "dbatools_<FGN>" Renames every FileGroup within HR to "dbatools_[the original FileGroup name]" .EXAMPLE PS C:\> Rename-DbaDatabase -SqlInstance sqlserver2014a -Database HR -DatabaseName "dbatools_<DBN>" -FileGroupName "<DBN>_<FGN>" Renames the HR database to "dbatools_HR", then renames every FileGroup within to "dbatools_HR_[the original FileGroup name]" .EXAMPLE PS C:\> Rename-DbaDatabase -SqlInstance sqlserver2014a -Database HR -FileGroupName "dbatools_<DBN>_<FGN>" PS C:\> Rename-DbaDatabase -SqlInstance sqlserver2014a -Database HR -DatabaseName "dbatools_<DBN>" Renames the HR database to "dbatools_HR", then renames every FileGroup within to "dbatools_HR_[the original FileGroup name]" .EXAMPLE PS C:\> Rename-DbaDatabase -SqlInstance sqlserver2014a -Database HR -DatabaseName "dbatools_<DBN>" -FileName "<DBN>_<FGN>_<FNN>" Renames the HR database to "dbatools_HR" and then all filenames as "dbatools_HR_[Name of the FileGroup]_[original_filename]" The db stays online (watch out!).
