## Overview This is the procedure for migrating Pleasanter 1.3 installed on Ubuntu to Pleasanter 1.4. For other distributions, please refer to their respective documentation. |Target|Before migration|After migration| |---|---|---| |OS|Ubuntu|Ubuntu| |DB|PostgreSQL|PostgreSQL| |Web server|Nginx|Nginx| |Platform|.NET 6.0|.NET 8.0| |Pleasanter|Pleasanter 1.3|Pleasanter 1.4| ## Prerequisites 1. Ensure the user running Pleasanter is registered. The **User who will launch Pleasanter** mentioned in the procedure refers to this user. ## Advance Confirmation Confirm the version of Pleasanter installed on Ubuntu. 1. Log in to Pleasanter. 1. Click "Help" in the upper right corner and select "Version". 1. Confirm that the version is "1.3.x.x". ## Notes 1. If you have edited the configuration file of the source environment (under the /web/pleasanter/Implem.Pleasanter/App_Data/Parameters directory), do not overwrite and copy it to the destination environment. If you overwrite it as is, it is possible that **the newly added parameters are lost**, so please use a diff tool such as WinMerge to merge only the changes into the new parameter file. WinMerge is used in this procedure. ## Preparation #### Tools to Use 1. WinSCP and WinMerge must be installed on the local PC (Windows). WinSCP: https://winscp.net/eng/download.php WinMerge: https://winmerge.org/ #### Backup Database 1.

Start WinSCP on the local PC and connect to the server. 2. Create a working folder (C:\migration) and a backup folder (C:\migration\backup) on the local PC. 3. Use WinSCP to move to the "/web" directory on the server. 4. Back up the "/web/pleasanter" directory on the server to "C:\migration\backup" on the local PC.  5. Log in to the server and delete the "/web/pleasanter" directory on the server. 6. Extract the file downloaded (Pleasanter_1.4.x.x.zip) to the "C:\migration" folder on the local PC. 7. Start WinMerge and compare the following two folders. 　①C:\migration\pleasanter\Implem.Pleasanter\App_Data\Parameters 　②C:\migration\backup\pleasanter\Implem.Pleasanter\App_Data\Parameters  8. Compare and modify each parameter file in folder ① above with the corresponding files in folder ② above.  9. Zip the "C:\migration\pleasanter" folder on the local PC. *Name the zip file "Pleasanter_1.4.x.x_merged.zip" for this procedure. 　　Pleasanter_1.4.x.x_merged.zip 　　　　└ pleasanter 　　　　　　├ Implem.CodeDefiner 　　　　　　└ Implem.Pleasanter 10. Use WinSCP to copy the above "Pleasanter_1.4.x.x_merged.zip" to the home directory of the working user on the server.  ## Start Pleasanter 1.
